Cancer is not one disease. It is an overgrowth of an organ or a part of your body. If you have an overgrowth in your brain, it can have problems and complications entirely different from an overgrowth of your thyroid gland.

Can soneone explain this better ? What do thay mean by types of cancer or not all cancer is the same?
Than why are some cancer there is a cure?
Basically what cancer is is a cell type in your body loses it’s regulation on it’s ability to divide. Cells normally divide to regenerate, but most of the time they’re in a resting state. Cancer occurs when the cells lose that regulation and begin dividing uncontrollably. They may also lose the outer cell markers which tell them to stay where they are and invade into surrounding or more distant structures. The overgrowth eventually can deplete energy stores (why cancer patients often look so gaunt) and can invade into surrounding tissues causing pain and/or failure of the invaded tissues. Not all cancers are the same, because they can arise from different cell types in the body. Different types of cancer behave differently as to where they invade and how aggressive they are. Some cancers are worse due to location. For example, a skin cancer is picked up early because you can see it, as opposed to a lung or pancreatic cancer which is in deep tissues and often don’t present until it is advanced.
Some cancers have a cure becau some cell types are more susceptible to the chemotherapeutic agents or radiation than others, or they can be removed surgically more easily. The really important thing with regards to cure is early diagnosis.
Does that help?
Cancer is a group of about 400 diseases.
Just as someone may have a virus, this could mean a cold, a stomach virus, measles, mumps or a whole range of other viruses.
Cancer has lots of different types.
People commonly refer to them by their location (eg, breast cancer, lung cancer, skin cancer) but it is also important what type of cell is the result (small cell, squamous cell, melanoma, etc).
In my case I had an odd combination, ductal carcinoma in situ (DCIS) which is one type of early breast cancer and small cell carcinoma in my left breast. Small cell carcinoma is normally found as lung cancer.
Because one of these was encasing the other in a single tumor, my risk of recurrence is much less than if they had been growing separately.

The statement you are referring to is saying cancer is an overgrowth of "organs", but it is really an overgrowth of abnormal "cells".
I basically agree with tiredsurgeon.
Abnormal cells without normal apoptosis (programmed cell death) which grow uncontrollably. Usually due to lack of sufficient body iodine for normal apoptosis.
