Cancer and lymphoedema. Lymphoedema may develop when a cancer blocks a lymph node or some lymph vessels. Or it can happen if you have treatment for cancer that removes or damages part of the lymphatic system. Surgery and radiotherapy to the lymph nodes can cause lymphoedema.n some types of cancer, doctors now do a test called a sentinel node biopsy. This can reduce the need to remove all the lymph nodes, which helps to reduce the risk of lymphoedema. The sentinel node is the first lymph node (or first few nodes) that fluid drains to from the area of the tumour.
A polyp is an extra piece of tissue that grows inside your body. Colonic polyps grow in the large intestine, or colon. Most polyps are not dangerous. However, some polyps may turn into cancer or already be cancer. To be safe, doctors remove polyps and test them. Polyps can be removed when a doctor examines the inside of the large intestine during a colonoscopy.
A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated.If no stalk is present, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, sinus(es) , urinary bladder and uterus.They may also occur elsewhere in the body where mucous membranes exist like the cervix, vocal folds, and small intestine.denomatous polyps, or adenomas, are polyps that grow on the lining of the colon and which carry a high risk of cancer. The adenomatous polyp is considered pre-malignant, i.e., likely to develop into colon cancer. The other types of polyps that can occur in the colon are the hyperplastic and inflammatory polyps.
