No, the River Niger does not cut the Tropic of Cancer.
Cells go through a cycle of replication that is normally regulated by a tumor-supressor gene (kind of like a red light for cells). During cancer, that part of the regulatory system is deactivated. What this means is cells can continuously replicated (kind of like a traffic jam).
Lung cancer
No, the Tropic of Cancer runs through Africa.
Oncogenesis
No , its actually called metastasis.
Metastasis can occur during any type of cancer. It can happen early on or not at all. It is the spread of cancer through different organs.
If you are asking if your blood can get cancer then No. Cancer cannot be found in blood although it can move into the bloodstream through certain forms of cancer i.e stomach cancer. Cancer is usually in the form of a tumor therefore it has to be on a part of the body.
Cancer can spread in the body through a process called metastasis, where cancer cells break away from the original tumor, travel through the bloodstream or lymphatic system, and form new tumors in other parts of the body. Metastatic cancer is more difficult to treat and is often associated with a poorer prognosis.
Not normally.
There is no such thing as "head" or "neck" cancer. Cancer is general term for the abnormal multiplying of cells because of a mutation in their DNA ie- a tumor( although, not all tumors are caused by cancer). Cancer can be fatal for many different reasons, but generally it is because tumors cause the organs that they are in to not function normally. When a tumor is contained it can usually be removed but the problem is, it can travel to other parts of your body through the "lymphatic system" which is called "metastasizing" Once this as occurred, a persons chances drop.
I am no expert, but I remember very clearly his section of my biology class. Basically, cells go through a few phases when they divide. Once a cell has officially replicated itself, it goes through a checking process to make sure that the new cell has the proper genetic make up and that no mistakes were made in the replication process. In cancer cells, this process is skipped. The "healthy" cells make "unhealthy" cancer cells, but don't realize it. The healthy cell then dies off because there is a cell to replace it. However, the cell taking its place is a cancer cell. The cancer cell then divides and makes more cancer cells. This is how cancer grows and replaces healthy tissue. Also, because the cells don't take the time to make sure the cell was replicated properly in the cancer process, the cancer cells grow faster because they don't stop to double check that their growth is proper.
Screening
Lung cancer is the leading cause of death in people with cancer. People normally die from smoking then getting lung cancer.
No, He has throat cancer. He is going through an aggressive process and is looking forward to recovering.
yes normally people would
Pleural mesothelioma is a very dangerous cancer. There are many different treatment options, but there are no gaurentees that these option will work.Since pleural mesothelioma is a cancer that not alot of doctors are specialized to treat, your first thing would be to contact a specialist. Since there are a few different treatments available for this cancer, the treatment time for each process varies depending on which form of treatment you decide to do or you or able to do based on what stage of the cancer you are in. For example if you decide that you would like to have the surgery to remove the cancer then you would have to account for the time of the surgery, recover time and some chemotherapy afterwards. Where if you were only able to have the chemotherapy the treatment process would be long depending on the stage of cancer you had. There is no definate time frame for any type of cancer
