The malignant cells that cause lymphoma begin at the lymph nodes. Tumor develops when there is an enlargement of the node. The case is quite similar to lymphoid leukemia, but this only involves the bone marrow where the blood cells are produced through the haematopoesis process as well as the circulating blood.
The first description of this dreaded disease was first published in 1832. This was done by Thomas Hodgkin, thus the name of the Hodgkin type of this illness. There are many other forms that have been discovered since then and all these are now part of a large group of illnesses that are known as hematological neoplasms.
When you start feeling that you have the symptoms, especially the enlarged lymph nodes, you should seek the help of your doctor. This case may not always mean that you are sick, but to make sure that you are okay, you have to get yourself checked by a professional. The first step that doctors may require you to undergo is biopsy, the type of which will be dictated as to the organs that are infected with the disease. After it was established that you already have it, the doctors will then try to categorize from which type of this illness you are suffering from. Before you can be given proper treatment for your condition, your bone marrow needs to be tested and you have to go through various tests and scans.
PET Scans
One of the special kinds of scans that you may be asked to undergo is PET scan or Positron Emission Tomography. This is able to determine the cancers based on the high activity that is happening on the cancer cell.
Other types of scans provide different results. For example, MR type and CT scans present good quality photographs of the various body parts where you can view the masses of tumors and swollen nodes. The problem with these scans is the fact that doctors cannot based their findings whether a person has the illness based on the size and shape of what was photographed through these processes. This is what PET scans are able to fill in the blanks.
PET scans are useful in the procedure because these are used to map out the disease on a person’s body. Along with the other kinds of tests, all results can be used to determine the stages of the disease. This is also able to find out if the lump that showed up on other tests, is cancerous or not. After the condition was settled, the doctor can then proceed to give the necessary treatment, whether you need to go through chemotherapy or it will be best to undergo radiation.
After some cycles of chemotherapy, you have to go through the same scans and it will help to assess how well your body is responding to it. When the treatment has been done, you still have to go through PET scans to know whether the lump still has cancer cells, scar tissue or it has already been healed.
