Whom Lymphatic cancer affects the most

Lymphocytes are specialized and very important cells of the human immune system and in a lymphoma patient these cells get affected and become cancerous. As a result immune response to bacterial and viral attack become weak. According to me lymphoma is the most dangerous type of cancer, as the sufferers realize it in the later stages.


There are two main age groups, which are likely to be affected from lymphoma, one is 25 to 35 and second is above 60s. Immune system of people above 60s become weak naturally and prone to infection, and as a consequence body is no longer able to eradicate the mutated cells and these cells multiply and change in to cancer. On the other hand researches had shown that 25 to 35 years old people are also more susceptible to this disorder.


There is a little bias in the disease regarding gender; men are three times more susceptible to the disease than women. Some scientists think that Female hormones may protect from disease, as the women become aged and hormone level decreases, the chances of developing lymphoma starts equal to their male counterparts. On the other hand male hormone make men more susceptible and with decrease in hormone level male become less prone to the disease.


Geographically Western countries like UK, America, Australia and Germany etc have higher incidences of lymphoma than Asia and Africa. Their rich lifestyle with alcohol and fatty foods and polluted environment with carcinogenic substances dispose westerners to lymphoma.


But, this not answerable why some people get affected and others not, while both are living in similar environment.

What Lymphoma cancer means?

What is Lymphatic cancer?


Lymphoma is a group of disease rather than a single disease in which the cells of the immune system become cancerous and start multiplying wildly in a lymph node. In the beginning a single lymph node can be affected but later cancer spread fast through lymphatic system in order to affect other nodes and also the other tissues, like bone marrow, become affected.


Immune cells including the T and the B cells which in turn are the two main defense mechanisms against infection and illness, become cancerous. These cells travels via blood through lymphatic system and hence lymphoma cancer can be very mobile and affect far located areas of body than original site of cancer. A sufferer due to the higher mobility of the lymphoma cancers often experiences symptoms like swollen lymph glands at other places but these may be related with cancer or other diseases like flu, because a lymphoma patient become less resistant even to the weakest of pathogens.


If you have swollen lymph glands that do not mean that you have lymphoma cancer because many other disease that requires immune system will produce mild swelling in the lymph glands. But if you feel swelling in the gland that is painless you should consult your doctor.


Hodgkin’s disease and non-Hodgkin’s Lymphoma are two main types of lymphoma cancer. In Hodgkin’s disease, painless enlargement of one or more lymph nodes, commonly in neck, chest and armpits takes place. Fevers, night sweats, weight loss and bone pain are main symptoms showing spreading of cancer from the initial sites. Non-Hodgkin’s lymphoma, more common of the two, can initiate in the same manner but the patient can also develops an enlarged spleen anemia and general malaise.


Lymphoma patient need not to be hopeless as it is diagnosable. Lymphoma patient Chemotherapy, radiation therapy or a bone marrow transplant can get rid from lymphoma cancer.
