What’s happening to me?

It's been some time, again, since I wrote last. In the meantime, I was going through something of a predicament.
In the middle of November last year, when I was talking with my clients at a meeting, I felt a hot flush in my face. I didn't care so much then, but when I went to the restroom and looked into a mirror, I found red rashes in my neck. "What's this?" I wondered but forgot about it until I was back home. The moment I took off my undershirt to take a bath, I was shocked to see the rashes spread all over my body. Something was definitely wrong with me!
The next day I went to see a doctor, who told me there were three possible causes for this type of rashes, the last one of which shocked me.
"Something might be wrong with your internal organs."
"What possibly might it be?" I asked him. Instead of answering my question he said.
"You look thinner than I saw you last. Don't you?"
"Now that you mention it, yes, I somehow lost my weight by 1 kilo in a matter of a month without doing anything special."
"Hmmm, You need to take a blood test."
"For what?"
"For something like liver functions and......"
" and what!!!?"
"And cancer markers."
