history: I would really like to enjoy more time out in the sun, but I'm worried I might get skin cancer. Any advice?
knowledge: There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma.
response: Well I don't have any advice for you, but I can tell you that there are 3 main kinds of skin cancer: squamous-cell an basal-cell skin cancers, and melanoma.

Well I've heard of melanoma before, but what's going on with those other two types? Are those more serious?
knowledge: Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death.
response: I'm not sure.  Basal-cell cancer can damage tissue around it.  It grows slowly, but it's not likely to cause death.

Hmm nice to know it won't necessarily kill you!  How does skin cancer progress?
knowledge: They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.
response: Oh, well abnormal cells develoop, which can spread or invade.

Maybe I should just be content to stay inside more often then. Getting a tan ain't worth chemotherapy.
knowledge: Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim to prolong life or to reduce symptoms (palliative chemotherapy).
response: Perhaps.  Although chemotherapy can reduce symptoms, prolong life, or have a curative intent.
