Why does lung cancer spread to the brain so often?

Lung cancer: The different cell types of lung cancer have the propensity to spread to different organs either due to blood stream patterns, adjacent anatomy or the affinity of these other organs to receive and grow these cancer strains. It turns out that the brain is one of those susceptible organs. ...Read more

Cancer (Definition)

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

Why does lung cancer usually spread to the brain, thereby producing brain tumors?

Why does lung cancer usually spread to the brain, thereby producing brain tumors?

Brain Mets: (metastasis) as an entity comprise 100k per year. Lung cancer leads the league, but breast, melanoma, kidney are quite common. Prostate almost never. Only rhabdoid tumors in children commonly go to brain. This pattern stares at us, but baffles us as to why "organotropic" patterns of metastasis are so predictable. ...Read more

Lung cancer has spread not to the brain but the bones actually, how long to live or what's the survival rate if i go through chemo?

Lung cancer has spread not to the brain but the bones actually, how long to live or what's the survival rate if i go through chemo?

Depends on a number : Of factors. Discuss with your team of docs (orthopod, oncologist, pcp & any other specialitist that you may need). Chemo/radiation are generally best options, with some surgical procedure to stabilize a broken or a bone that is weakened (but not yet broken). The idea is to improve the quality of life for as long as possible. Survival is dependent on cancer type and its response to the meds.. ...Read more

How likely is it for someone to survive brain cancer and tuberculosis in the lungs?

How likely is it for someone to survive brain cancer and tuberculosis in the lungs?

Tb chances are good: It is quite unlikely to have both conditions at the same time. This makes therapy more challenging but doable. Cure from tuberculosis should be expected. The main concern here is the brain cancer. For the most common adult brain cancer, survival is about a year, give or take a few months. ...Read more

Once cancer has developed to stage 4, when it spread to different organs and chemo is given, does this remove cancer or is the organ itself cancerous?

Once cancer has developed to stage 4, when it spread to different organs and chemo is given, does this remove cancer or is the organ itself cancerous?

The organ is Ok: Cancer involved different organs as isolated scattered tumor nodules. With a good/effective chemo, the tumor nodules shrink and can sometimes disappear completely. The remaining organ is healthy and functions normally once cancer has been killed by the chemo. ...Read more

How long does it take for testicular cancer to spred to the abdomen and brain? Is spreading to the brain common?

How long does it take for testicular cancer to spred to the abdomen and brain? Is spreading to the brain common?

Depends on the type: Testicular cancer is usually confined to the testicle, but spread to other organs, metastases, do occur. The type of primary testicular tumor and it's pathologic features determine both the chances of metastasis and if so, where. In particular, choriocarcinoma, a very rare type of testicular cancer, has been associated with brain metastases. Thankfully, brain mets are very rare. ...Read more

Why dont lung cancer patients usually get lung transplants? Wouldnt this be better than chemo or radiation to get rid of the cancer lung?

Why dont lung cancer patients usually get lung transplants? Wouldnt this be better than chemo or radiation to get rid of the cancer lung?

Lung cancer spreads: Transplants are only useful if we can first eradicate the cancer, which is not possible in the case of Lung cancer. Further there is reduced immunity following transplants which encourages the cancer to grow faster and spread as the immune system is what keeps the Cancer under check for most of the time. ...Read more

Stage 4 cancer that has mets to brain, lungs, adrenal gland and now liver, cause bowels to shut down? If so what are the signs that it is happening?

Stage 4 cancer that has mets to brain, lungs, adrenal gland and now liver, cause bowels to shut down? If so what are the signs that it is happening?

It depends on so man: Bowel obstruction can occur in any advanced abdominal cancer. If the bowels are compromised by tumor they can close/obstruct. It is not difficult to tell when that happens because no food will pass through them. As a result patients become constipated/obstipated and have increasing pain in the abdomen and are unable to eat and drink due to persistent nausea and vomiting. The belly swells up also. ...Read more

Why is secondary liver cancer from the colon cancer so hard to treat?

Why is secondary liver cancer from the colon cancer so hard to treat?

Colon ca mets: To live is hard to treat because many times the metastasis is on multiple lobe of the liver and cannot be surgically removed. Surgeon only do surgery with the intention of cure if they can remove the metastasis completely. If surgery is not possible you should still consider chemotherapy. The quality of life is still pretty good even if not cured. ...Read more

Very: About 60, 000 americans each year have a primary lung cancer that's spread to the brain by the time it kills them. Radiaton may help, but the prospect of death by squeezing the brain out of the base of the skull is only one of the many horrors of lung cancer. ...Read more

Why do breast cancer cells break away from the tumor and spread to other ograns of the body?

Why do breast cancer cells break away from the tumor and spread to other ograns of the body?

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 more

Lung (Definition)

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
