B. SWOLLEN LYMPH NODES

Sometimes, swelling of the lymph nodes may occur and can be a serious sign of progressing cancer. You’ll need to get professional help depending on the degree to which your glands remain swollen after three to four weeks. While it may necessarily be cancer of the lymph nodes, it can still be a sign of another form of cancer.

Also, cancer may start to spread from the lymphatic system to anywhere else in the body, such as non-Hodgkin lymphoma and Hodgkin lymphoma. Some cases, however, may just be caused by infections or other immune system diseases that may clear up as your body heals.
