How many different types of cancers are there?

There are out of the entire alphabet 19 letters have at least 2 different type of cancer in them. The letters that do not have cancer type in them are d, f, j, q, x, y, and z, but the other letters have cancers. In the letter A they're 8 different types of cancer in the link it has more but so are repeated. Some people have lost their life in the battle with cancer and we all have lost a family member or a friend. I lost a family member this weekend. Though I did not know her, my grandma was sad. My aunt said that she was my cousin-in-law and she explained it all to me how she was. My last year science teacher's son had four tumors in his stomach and had to go through surgery to get the first tumor out and they did test on that tumor. So they started him on kemo therapy.
