How does cancer start in your skin?

My friend’s brother has been diagnosed with cancer for the second time, I would like to donate as a Christmas present to the most honerable cancer research place.

There is no right or wrong, because it is basically hypothetical.
Let’s just say, cancer of the liver, how many times has the body defeated the cancer before the cancer wins and starts to attack the body?.
Personally, I think several times at least.

How do they know that it comes from a particular organ if it is in the lymph nodes? Does each type of cancer have a cancer print? Is there a machine that can detect this?

My friend just found out that she has breast cancer in her right breast but three different lump types of cancer in one breast, and it has effected her lymph nodes at least two of them. What are her chances and what stage cancer would that be? She is going to be having a mascetomy and chemo.

Can cancer be so hereditary as to skip every other generation in a family? On my dad’s side of the family it seems like it does. Both my great grandmothers on my father’s side had cancer (breast cancer and another type) and a great grandfather had cancer as well. My grandparents did not have cancer. My father ended up having cancer out of the three of my grandparents children. Me nor any of my cousins have had cancer. Is it possible any of our children will?

I heard that a lump that is painless cud be cancer. Could it be cancer if it is painful. Also, how fast does testicular cancer spread. I’m rly nervous about this!!!

Is there a good website to look up this information? I tried googling it I’m not getting any good results.
I’m just curious as to what types of cancer I should be aware or concerned about. I am 18 and I know I shouldn’t be too concerned about cancer at this age, but it does happen.
I don’t know my medical history and I have no idea whether my family has a history of cancer or not.

My co-worker's brother has cancer, and Cancer Treatment Centers of America is not accepted by his insurance. What other options are available?
My Co-worker's brother has cancer, and his insurance does not accept Cancer Treatment Centers of America. He lives in Virginia, but somewhere in North Carolina should be ok also. Thank you so much.

I know close to nothing about cancer. My mum has been recently diagnosed with breast cancer, and from the state she is in, my view is that it is too late for any treatment. (Sorry for being vague here, I find it too difficult to describe her body. She is physically extremely weak already).
All sorts of tests are being done currently to assess the situation. Before the doctors give us some feed back, I am just wondering if anybody has experiences to relate. Also, do you know of people who have been saved with chemio "at the last minute"? (In her case, it is too late for all other treatments, as doctors told her). Thank you.
