Cancer is an abnormal cell growth in the body part which multiplies at an uncontrollable rate. Also known as malignancy, it is not self contained but has to ability to multiply and spread to other parts of the body through the bloodstream and lymphatic system. These malignant cells invade other tissue and organs in the body to form tumour, this process is known as metastasis. Metastasis tumour is the same kind as the primary tumour that formed originally. Metastasis causes damage in important organs such as lungs, brain, liver, colon and so on. Cancer cells travel throughout the body via blood vessels or lymph system. During their journey, they emerge from blood vessel walls to form a new tumour.
If cancer starts in the lungs and spreads to the colon through metastasis, the tumour in the colon is treated as lung cancer and not colon cancer. Researchers are aiming their studies on how to stop the growth of primary cancer cells and metastasis. The origin of primary cancer where it started from is often unknown, therefore locating cancer growth pattern could save more lives. Cancer treatment options include Chemotherapy, Targeted Therapy, Hormonal Therapy, Biological Therapy, Surgery, Radiations and Oral medications. Doctors treat cancer as long term chronic disease and patients should follow up on a regular basis.
