My friend is 16 years old, he is 90 pounds and 5'8". I've been trying to find reasonable explinations for this kind of weight. Is it Normal? However a few days ago he scheduled an appointment with the doctor, he told me stuff, symptoms, that i didn't realize existed. Whenever he would eat he would feel so sick afterwards, have to crawl into a ball, or would want to cry. It got so bad that he was afraid to eat. He hasnt been able to have a bowel movement in forever. A Long time. He has swollen lymph nodes and coughs all the time. His mother didn't want to take him to the doctor. So he has rescheduled, again. He said he thinks he has rectal cancer. And now ive researched it, And it really scares me. Is there a possibility that he could very well have this disease? And is it also possible that it could be a number of other Less serious conditions?
