How Do Cancerous Cells Spread From The Lungs To The Other Parts Of The Body
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
We hope not.: What makes a cancer "evil" is the ability of cancer cells to travel outside of the organ where they arose and take over another organ; this is how cancer can be life-threatening. In advanced cases of cancer, we can identify these "invaders", but most often, these cells are present but undetectable. The stage of the cancer gives us an estimate of this probability, leading to the rec for chemorx. ...Read moreSee 1 more doctor answer
Does the surgical removal of a cancerous tumor necessarily result in cancer cells to be spread to other parts of the body via the bloodstream?
Cancer treatment: No. If the neoplasm is thought to be limited and amenable to excision or complete removal, then it is the treatment of choice. Adjuvant chemo and/or radiation are used to kill residual microscopic local or distant metastatic disease. It is not a good idea to just debulk the malignancy. The goal is to excise or remove entirely all gross disease. What "spills" in blood stream is insignificant. ...Read more
The Nature of Cancer: What makes a tumor malignant is the potential to break away from its organ of origin and take up residence in another one. Some cancer cells are better than others at travelling; others have more of a tendency to travel the longer they have been untreated. If we really understood the "why" part, we would be that much closer to curing all cancer. ...Read moreSee 1 more doctor answer
Lymphatics usually: When a cancer invades a tissue, it can enter into the drainage system of the body called the lymphatic system (lymph glands). These act like pipelines to the various areas of the body and transport the cancer to other organs. Sometimes this happens through the blood stream, but most often through the lymphatics. ...Read more

Can you tell me about angiogenesis promoting both the growth of cancers and the metastasis of cancer cells to other sites in the body?
Poor response: Tumors grow in general in an anaerobic media and require hyperbaric oxygen to destroy. Folkman developed drug angiostatin which failed to prevent cancer spread. Avastin (bevacizumab) which is an anti vegf drug doesn't destroy blood supply. It appears to help by opening microvasculature to tumors to let chemo enter more effectively. Blood vessels in tumors are the conduit for vessel invasion by tumor cells. ...Read more
I have a TB on the lymph node.Do the bacteria can spread to the other parts on the body especially lungs?
Yes, tuberculosis: Is an infection caused by bacterium. It can affect any organ. You need to have proper anti-tb treatment. ...Read more
Good: Breast Cancer like all malignancies is programmed to spread. When first appearing as a lesion growing out of the milk duct, it remains in-situ for a period of time because clones or populations that spread havnt formed. As early mutations occur new populations of cells will leave the primary to spread, so that the rule is: The earlier the diagnosis the better the chance of cure. ...Read more
Does cancer generally spread from original tumors to other parts of the body, or does it just start in other part?

What is the mechanism in which cancer kills? Do the masses interfere with proper organ function? Or do cancers put off toxins in the body? Or what?
How doesCA kill: Cancer cells grow,requiring energy, disrupting normal organ function and can even growing into vital structures like blood vessels.Left untxed CA will essentially drain the person, why they loose wt, and eat into adjacent organs. It can also spread gaining access to other organs. ...Read moreSee 1 more doctor answer
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
