Patient discussion about Malignant

Q. how many types of cancer are they?

A. There are over 200 different types of cancer. You can develop cancer in any body organ. There are over 60 different organs in the body where you can get a cancer.

Each organ is made up of several different tissue types. For example, there is usually a surface covering of skin or epithelial tissue. Underneath that there will be some connective tissue, often containing gland cells. Underneath that there is often a layer of muscle tissue and so on. Each type of tissue is made up of specific types of cells. Cancer can develop in just about any type of cell in the body. So there is almost always more than one type of cancer that can develop in any one organ.

Q. why does it call "cancer"?can you treat cancer?

A. the name came from the appearance of the cut surface of a solid malignant tumour, with the veins stretched on all sides as the animal the crab has its feet, whence it derives its name. Hippocrates first called it in that name after describing few types of cancer.
some of the cancers are treatable but that is a big subject. there are some very nice videos here on the site that can give you a clue about that. just search them there ^ :)

Q. Cancer - incurable? When i was surfing the internet for the incurable disease, i found CANCER is one among them. Is there not a medicine found yet? Really is it incurable?

A. I like to share with you what i read from a book it said 'With modern day treatments many cancers are completely cured but unfortunately there are still many others which are not.

Although it is not always possible to be certain, doctors are often able to tell whether or not a particular cancer might be cured. Even if cancer is incurable they will usually still offer treatment in the hope of prolonging life and, controlling, symptoms.'
