Types of Cancer in Dogs


Lymphosarcoma is one of the most common types of cancers seen. It is also referred to as lymphoma or non-Hodgkin's lymphoma. In dogs, many different species develop Lymphosarcoma. Like any other cancer, this one can "metastasize", which means it can spread and affect other organs and tissues.

Most dogs get a type of Lymphosarcoma that originates the lymph nodes and usually the nodes under the jaw get swollen. Sometimes this is the only symptom your dog will have. But the jaw is not the only place where this disease can begin. Some forms of Lymphosarcoma begin in the bone marrow, the chest, abdomen, or even the skin.

RENAL LYMPHOSARCOMA

When the disease attacks the kidney first, the illness is called Renal Lymphosarcoma. The symptoms include drinking a lot of fluids and urinating a lot. Also vomiting can appear and also loss of appetite. The pet can even get depressed.

MEDIASTINAL LYMPHOSARCOMA

The Mediastinum is the tissue near the heart and lungs. The cancer creates a tumor there and the pet has hard time breathing and the lung accumulate fluid.

BONE MARROW LYMPHOSARCOMA: LEUKEMIA

When the cancer has started or reaches the bone marrow, then it is called Leukemia. The cancer affects the blood. The bone marrow's role is to create red blood cells that carry oxygen, white blood cells that destroy infection and platelets that help blood to clot. The cancer causes these types of cells to drop in numbers and it causes: infections, anemia and bleeding disorders.

DIAGNOSIS

The vets do a tissue biopsy to determine the disease. Is the microscopic analysis of the tissue reveals that the disease is present, a detailed exam follows. This exam will show if the disease has spread in other body areas. The vets call this "STAGING".

The diagnostic Procedures used to "STAGE" include:

- Different blood tests

- Cytology - analyzing cells in the large lymph nodes and taking a look at them under the microscope. - X-Rays

- Ultrasound

- Bone Marrow Analysis

Staging helps the doctors figuring out the best way of treatment.

TREATMENT

More than 90 perfect of the dogs that get chemotherapy go into remission. This is not a cure but just a stage when quality of life is assured. A dog will normally have a stage of remission of about eight to ten months. Also, the dogs don't get as many side effects as humans do. Less than 5% of the dogs get side effects like diarrhea, vomiting, loss of appetite, weakness and lethargy.

The dogs don't lose their hair after chemo, like people do. Only a few breeds get these side effects: Poodles and Old English Sheepdogs). Usually even they only lose their whiskers.

CANCER DIETS
When a dog undergoes a cancer treatment, it must have a good diet with lots of vitamins.

Types, Symptoms and Diagnosis of Blood Disorders


It's really hard to ignore the role blood plays in our body. It is one of the most important living tissues made up of liquids and solids. While, the liquid part, primarily known as plasma, is made of water, salts and protein, the other half of your blood is plasma. Apart from this, the solid part of your blood contains red blood cells, white blood cells and platelets. Any malfunction of red blood or white blood cells can lead to various blood disorders. In fact, at times blood disorders can lead to poor blood clotting and continuous bleeding. The disorders can result from defects in the blood vessels or from abnormalities in the blood itself. Today there are various types of blood disorders that must not be ignored as each blood disease have its own complication and require proper clinical care. Here are some of most serious blood disorders and best diagnosis method that can help you in knowing and curing blood disorders:

Anemia- It is one of is the most common blood disorder that occurs when the ratio of red blood cells or concentration of hemoglobin gets reduced in the blood. Though at times anemia itself is considered as symptom of a disease rather than a disease itself, but there are few major symptoms that must not be ignored and need to taken care of, like increased heart rate (tachycardia), difficulty in catching a breath, tiring easily and frequently, yellowing of skin, eyes, and enlarged spleen or liver. It can be cured very easily. The sooner you get to know the better it may help you in curing it properly. The most common diagnostic procedures that you can follow are blood test and bone marrow aspiration and/or biopsy.

Hemolytic Anemia- Hemolytic anemia is another blood disorder in which the red blood cells are destroyed faster than the bone marrow can produce them. Basically, this type of disorder can be classified into two categories:

Intrinsic- In this type of blood disorder, the destruction of the red blood cells takes place because of the fault within the red blood cells themselves.

Extrinsic- In this type of disorder, though red blood cells are developed but later it get destroyed by getting trapped in the infection, spleen, or from drugs that can affect red blood cells.

The major symptoms of this type of blood disorder are weakness, intolerance of various physical activities and dark color of urine. Apart from this, it can be diagnosed through methods like blood test, urine test and bone marrow aspiration and/or biopsy.

Thalassemia - Thalassemia is an inherited disorder that majorly affects the production of normal hemoglobin that carries oxygen to the tissues in the body. Thalassemia includes a number of different forms of anemia. However, the seriousness of this blood disorder basically depends on the number of genes that are affected. This blood disease can be easily diagnosed by blood test. Though, thalassemias also get passed on from parents to children therefore family genetic studies can also help in proper diagnose of this disease. This generally involves taking records of a family medical history and performing blood tests on family members to find out whether there are any missing or altered hemoglobin genes.

Porphyria - It is another category of blood disorder that is primarily caused due to the abnormalities that in turn leads in the production of a chemical compound called Heme. Now Heme is an important substance that is majorly produced by the body and the bone marrow and blood is the most vital content that holds the Heme. Generally, this blood disease is not easy to diagnose, but yet it can be checked by conducting a number of tests of the blood, urine and the stool.

Hemophilia - This disorder also known as hemophilia is hereditary bleeding disorder that is majorly caused by a shortage of a substance necessary for blood clotting. The lack of ability of blood to clot, or coagulate, leading to excessive bleeding, even from slight injuries is the trademark of Hemophilia. Although the density of symptoms may differ with this disease, but the disease is typical for the bleeding and typically occurs if an infant is circumcised. It can be analyzed by performing a set of blood tests.

These are some of the major blood disorders. Though each of them has its own way of analyzing or diagnosing, but each can be cured easily. All you need to do is take care of its symptoms and follow suitable curing procedure.

What Types of Specimens Are Stored in a Bio Bank


Bio bank is a sort of bank where biological materials like animals, plants and humans are collected, stored and distributed. Biological materials are researched and assessed over here in a proper systemized manner. It is a place for a source of advancement in scientific knowledge.

Human bodily substance like blood, DNA, cells and tissue are collected as samples from a large number of people to get genetic information related to their medical history, and lifestyle data are stored in this bank. The record is stored in bio bank to see from where the problem actually originates. Bio bank has the collection of both the samples and their data.

Various types of specimen can be found in bio banks, like surgical and transplant tissue, cancer or tumour tissue, cord blood or stem cell bank, blood bank having dried blood spots, body fluids (synovial, urine, sputum, bucaal scrapings and sperm), DNA and RNA bank, and cornea bank.

The types and purpose of samples in bio bank vary from one another. They are collected for different types of illness as cancer types and tumour bank. They are collected in connection with the clinical trials or public health surveys. The sampling and database are done after taking the ethical permission.

These specimens are investigated for various purposes like certain disorders. Tissue specimen, taken from certain DNA from the databases, provides an opportunity to the whole mechanism of a disease, and then the development of the drug for that particular disease and also the effect of that drug.

Today, different types of tissues are stored in these banks so that a disease can be analyzed with all its complexities and can be treated on modern technology. There are two types of tissues; one is surgical tissue and the other is transplant tissue. The security of genetic donors in these banks is anonymous, that is, they are given some code number instead of personal information.

These bio banks are known for transfusions. The "blood bank" collects blood from volunteers and donor for some sort of surgical inventions and transplantation. As in case of "eye bank", it is responsible for the collection and storage of cornea tissue and its transmission to other hospitals for transplantation. The "DNA bio bank" is responsible for storing blood samples so that the researcher can study the cause of disease and disclose its solution, so that people can lead a healthy life. Bio bank plays a significant role in the field of medical research today.

These banks also monitor the problem arises after outbreak of a certain disease or pollution. These banks collect cancer samples, normal samples and non-neoplastic diseases. They have both solid and liquid tissue. Solid tissue includes (surgical resections, image-guided biopsies, bone marrow biopsies and endoscopic biopsies) and liquid tissue includes (peripheral blood, genomic DNA, plasma and Serum).

Bio specimens are collected from blood and tissue samples of healthy people and also from cancer patients with their consent to diagnose cancer. Medical and personal information of the patients and the donor is also collected for the link up of the disease. The specimen which is collected from surgery is used for the research and study about that particular disease.

What Are the Different Types of Biopsy Needles?


Biopsy needles are of utmost importance in the diagnosis of certain diseases such as cancer and the likes. Doctors get samples of the tissues that need to be studied in order to get a better picture of what is really the general status of the organ or other parts of the body that needs evaluation. Before a doctor will perform surgery, he will need to acquire a sample specimen first and have it sent to the histopathology section of the hospital laboratory where it is processed and read by a pathologist to determine if the object of inspection has cancer or free from it.

In some cases, the surgeon may require a small chunk of the organ or part to be examined, while in other cases all that is needed are really small amounts of flesh or fluid as a sample. In this case, they are used to extract the sample directly from the organ or part to be tested.

The biopsy needle types largely depend on its purpose and also the organ involved in the biopsy. For example, percutaneous liver biopsies use aspiration or asuction type needles, for their oblique tip that has slightly convex tip as it extends outward. Another type of needles used are the cutting type needles also know as the automatic biopsy needles. They are spring loaded and once triggered, it slices in a rapid-firing side-notch manner cutting through parenchyma cells of the liver.

For lung biopsies, coaxial needles are used. They are characterized by its increased rigidity and torque, which can overcome any resistance from the surrounding soft tissues and can collect multiple samples from a single procedure. Additionally, single shaft needles can also be used, since they are more flexible and maneuverable than the previous needle. They also puncture through soft tissues easily provided that no heavy tissue resistance is present. Nonetheless, a cutting needle, due to the barbed edges that enable the needle to cut large tissue samples from the pulmonary nodule, also works well. A 14 to 21 gauge needle can be used and can also be incorporated in a biopsy gun.

There are also soft tissue needles and bone marrow needles. The soft tissue needle are specifically made to capture good quality soft tissue samples while minimizing trauma to the patient. While bone marrow needles are very rigid, which allow them to drill through bones to acquire bone marrow samples.

Performing biopsies takes a lot of practice and training in order to hit the right spot that the doctor is aiming. To assist the physicians in hitting the right spot the first time, they normally use needle guides These needle guides are incorporated into the needles itself. They are usually 0.55-0.9mm wide and are usually placed on the tip of the needle. This will enable the clinician to see the direction of the biopsy needles inside the body. Compared to puncturing the site blind and without any idea what you might hit, these needle guides make it easier for the clinician to be accurate and eliminate critical errors in operation.

Medical and personal information of the patients and the donor is also collected for the link up of the disease. The specimen which is collected from surgery is used for the research and study about that particular disease.

What Are the Different Types of Biopsy Needles?


Biopsy needles are of utmost importance in the diagnosis of certain diseases such as cancer and the likes. Doctors get samples of the tissues that need to be studied in order to get a better picture of what is really the general status of the organ or other parts of the body that needs evaluation. Before a doctor will perform surgery, he will need to acquire a sample specimen first and have it sent to the histopathology section of the hospital laboratory where it is processed and read by a pathologist to determine if the object of inspection has cancer or free from it.

In some cases, the surgeon may require a small chunk of the organ or part to be examined, while in other cases all that is needed are really small amounts of flesh or fluid as a sample. In this case, they are used to extract the sample directly from the organ or part to be tested.

The biopsy needle types largely depend on its purpose and also the organ involved in the biopsy. For example, percutaneous liver biopsies use aspiration or asuction type needles, for their oblique tip that has slightly convex tip as it extends outward. Another type of needles used are the cutting type needles also know as the automatic biopsy needles. They are spring loaded and once triggered, it slices in a rapid-firing side-notch manner cutting through parenchyma cells of the liver.

For lung biopsies, coaxial needles are used. They are characterized by its increased rigidity and torque, which can overcome any resistance from the surrounding soft tissues and can collect multiple samples from a single procedure. Additionally, single shaft needles can also be used, since they are more flexible and maneuverable than the previous needle. They also puncture through soft tissues easily provided that no heavy tissue resistance is present. Nonetheless, a cutting needle, due to the barbed edges that enable the needle to cut large tissue samples from the pulmonary nodule, also works well. A 14 to 21 gauge needle can be used and can also be incorporated in a biopsy gun.

There are also soft tissue needles and bone marrow needles. The soft tissue needle are specifically made to capture good quality soft tissue samples while minimizing trauma to the patient. While bone marrow needles are very rigid, which allow them to drill through bones to acquire bone marrow samples.

Performing biopsies takes a lot of practice and training in order to hit the right spot that the doctor is aiming. To assist the physicians in hitting the right spot the first time, they normally use needle guides These needle guides are incorporated into the needles itself. They are usually 0.55-0.9mm wide and are usually placed on the tip of the needle. This will enable the clinician to see the direction of the biopsy needles inside the body. Compared to puncturing the site blind and without any idea what you might hit, these needle guides make it easier for the clinician to be accurate and eliminate critical errors in operation.
