Hi. Im 20 years old. Initially i thought my ilness could be lymphoma as i felt a swollen lymph node behind my head after having a tension headache(dull ache on temples,neck with some pressure on scalp) for like a week. I also noticed my weight had dropped. So i spoke to gp by phone and had my blood test done straight away so im waiting for my result now.  However I think i may have some form of bowel cancer as ive started noticing changes in my bowel mivements today. My stool is smaller, broken up and not the 'normal shape' a healthy bowel would indicate. No pains or bleeding so far.  Maybe its because im worried but my gut instinct is that there could be an underlying problem. Currently i have 2 lymoh nodes swollen. Im hoping its just some infection but ive read bowel cancer is common in UK so ive mentally prepared myself. Has any one else experiences these symptoms? Thanks
