How Does Malignant Melanoma Spread
Can Spread Quickly: Nodular melanomas tend to grow up as a nodule, and down into the skin. With melanomas, the deeper it is into the skin, the more likely it is to spread. So ask your doctor the depth of penetration in millimeters or the clarks level. Prognosis depends on the depth of penetration, and not the type of melanoma. ...Read moreSee 3 more doctor answers
Malignant melanoma is a cancer that begins usually in the pigmented cells (melanocytes) of the skin. It is generally considered the most dangerous form of skin cancer. Most cases are localized and caught fairly early but some people will develop widespread ...Read more
Enters circulation: The biology behind it is complicated and has been studied for decades by cancer researchers. However in a nutshell, the tumor gains access to blood vessels and lymphatics where it can then travel to distant sites such as lymph nodes, liver, lung, brain, and bones most commonly. ...Read moreSee 1 more doctor answer
Very variable: This varies with cancer type and route of spread among other factors. At the time of diagnosis, small cell lung cancer is more often already spread to other organs. Non-small cell cancer can stay as small lung nodules for a couple of years before picking up speed. Spreading via the blood vessels can be sometimes faster than spread through the lymph nodes. ...Read moreSee 1 more doctor answer
Unpredictable: Colon cancer spread to local lymph nodes and then on to other organs such as liver, lungs, bones. It can spread through the blood vessels or locally to other organs such as kidneys, prostate, etc. Rate of spread is unpredictable at present and likely depends on growth factors, cancer differentiation, and unknown factors. Of cancers that comeback after surgery, most (80%) do so within 3 years. ...Read moreSee 1 more doctor answer
It depends: Tumors that are grade 3, or that have a high "proliferation rate", may spread more quickly than grade 1 or 2. Tumors that are er- (estrogen receptor negative) or her2+ spread more quickly than other types. Inflammatory breast cancer of any type can spread in days; the other types of invasive ductal carcinoma generally take months. ...Read moreSee 1 more doctor answer
Lymph nodes: Lymph nodes are the way colon cancer cells usually escape the colon. It can grow through the colon into the surroundings. Finally it can move from lymph nodes into the blood stream that flows to the liver. When the colon is examined, and if lymph nodes are involved, chemotherapy is recommended. ...Read moreSee 1 more doctor answer
IT DEPENDS: It depends on the type of cancer and and the part of body is effected by it some cancers spread very fast and others are slow in their spread to other organs and parts of your body so all cancers are not alike and so the sprerad is not the same for different cancers in different organ systems and parts of your body. ...Read more
3 Basic Ways: Breast cancer can spread in 3 basic ways - it can grow larger and larger, invading into the skin or muscle; it can invade into the blood vessels and then travel to other areas of the body (most commonly liver, lungs, bone and brain), and it can invade into the lymphatic vessels and travel to the lymph nodes under the arm and other areas of the body. ...Read moreSee 2 more doctor answers
Can be quick, but: Could be years or never. You do not mention: size; stage, nodes + or -, age, receptor status (er, pr, her-2-neu). Breast cancer treatment can effect chance of relapse. I find the questions about speed odd...The true answer is we do not know in an individual what will happen, and rely on group statistics to frame what we tell patients. I emphasize, that individual may not behave like a group. ...Read more
Via blood and lymph: Like other cancers, melanomas spread (metastasize) via 2 pathways. First, via the lymph system, where the tumor gets caught in lymph nodes. Sentinel node biopsy is helpful to determine lymph node involvement. Next, it can spread via the blood. That's how melanoma can go from your skin anywhere to the brain, lung, liver, etc. It's propensity to do this makes melanoma so dangerous. ...Read moreSee 2 more doctor answers
It can spread quickl: Primary malignancies of bone like osteosarcoma, ewing sarcoma and chondrosarcoma can metastasize most commonly to the lungs and other bones. However, the speed at which this happens truly depends on the underlying biologic aggresiveness of the individual cancer. It is hard nearly impossible to determine the speed of spread with our current understanding and tools available for evaluation. ...Read moreSee 1 more doctor answer
