What is Cancer?

There are quite a few manifestations of malignant tumors – Burkitt Lymphoma and Retinoblastoma and Thymoma and Ovarian Low Malignant Potential TumorÂ and Small Cell Lung Cancer and Head and Neck Cancer – just to list a couple of examples. But, all of these tumors have a few things in common.

Loss of Control

Each cell in the body is influenced by hormones like Adrenocorticotropic hormone and Prostacyclin from outside the cell and some other chemicals in the cells. These regulating chemicals will control the actions of the cell. They will pass on to the cells when to grow and how much, when to be inactive and how they should interact with other cells.

Cancer cells have those controls shut off. They do their own thing without limit. They are always active at the maximum level. These malignant cells also lose their control of interacting with their neighboring cells and then can mobilize and go to other parts of the body.

Changes in DNA

All malignacies have lost their controls because the DNA in the cell has been damaged. DNA is the chemical programming in the cell that determines all of its activities. That DNA is damaged by being broken, nuclear radiation or chemicals. The DNA will start to act out of control. Viruses have also been shown to cause the DNA damage leading to a cancerous tumor.

Damaged DNA can also be passed to your children. That DNA can produce a malignant tumor if there is either some trigger that the cell contacts or further damage to that DNA.

Immortal Cells

Your cells in the body normally will only live a certain amount of time and then die (with some exceptions). They will then be replaced by new healthy cells. Cancer cells don’t normally die. Even when they are extremely abnormal, they just keep growing. Then those cells produce tumors and spread.

You live under the delusion that you can fix everything that isn’t perfect. That’s why you married a man who was dying of cancer. You don’t love, you need. And now that your husband is dead, you’re looking for your new charity case. That’s why you’re going out with me. I’m twice your age, I’m not great-looking, I’m not charming; I’m not even nice. What I am is what you need. I’m damaged. Dr. House

Types of Cancer

All of those types of cancer can be grouped into five common types. Those are Central nervous system cancers, Leukemia, Carcinoma, Sarcoma as well as Lymphoma and Myeloma.

Central nervous system cancers – these are cancer tumors that start in the brain and spinal cord. Leukemia – these cancers start in the tissues that produce blood – such as the bone marrow – and then release the cells into the blood. Carcinoma – these are cancers that start in the skin or the tissues that line internal organs. Sarcoma – Sarcomas are cancer tumors that start in connective tissue. Connective tissue is the tissue between the organs and other structures. Those tissues include things like fat, bone, muscle, blood vessels and cartilage. Lymphoma and myeloma – these cancers start in the cells that normally protect the body – the immune system.

Now that you know what a cancer is, you can learn how to possibly prevent it, or if needed how to treat it.
