During the cancer diagnosis, doctors look for the site of origin of the tumor and the type of cells.
Cancers arise in any organ. The body site, where cancer develops first, is the primary site. The tumor
spreads (metastasizes) afterwards. Common cancers include skin, lungs, breasts, prostate, colon and
uterine tumors. There are many signs and symptoms of cancer. Doctors may find tumors directly, by
X-ray or MRI imaging, or by using lab tests.
However, these signs and symptoms of cancer may mimic other diseases. Weight loss and abdominal
pain may mean stomach cancer or an ulcer. Weight loss and swollen lymph nodes may mean lymphoma
or AIDS or tuberculosis. Blood in urine is a sign of bladder or kidney cancer or a kidney infection.
Blood in stool is a sign of many bowel problems, not just cancer. Benign looking skin mole may be
deadly melanoma. Doctors often need a biopsy (microscopic check of tissues samples) to diagnose
cancer. The cancer type is found by microscopic examination. If the type is different from surrounding
tissue, the cancer probably came from another primary site. Metastases can spread directly or through
blood vessels, and lymphatic vessels. Biopsy helps to find the primary site. Treatment also depends on
the cancer cell type. Cells could be more or less differentiated and originate from different layers of the
same organ. If the cancer cells resemble healthy, mature cells, they are differentiated. Undifferentiated
cells look like very immature primitive cells. Checking the differentiation allows doctors to know how
aggressive the cancer is. Grade one cancer is less aggressive than grade four usually.
Also doctors classify cancers by stage. Stage depends on the size and spreading of the tumor. Stage
determines the mode of treatment - Whether it is surgical, radiation, chemotherapy and so on.
