Terrified I have cancer?

[Upsydaisy2017]

In the past 2 weeks my cousin (30) has been diagnosed with terminal bowel cancer and my partner's friends girlfriend (24) has been diagnosed with it.
Please tell me if I sound like a hypocondriac but I'm terrified that I have it, or at least some kind of cancer. I'm 29 and a couple of years ago I had blood in my stool so I had a sample done and a sigmoidoscopy which he didn't find anything but he said some areas were unclear as I hadn't done the enema well enough.
For over a week I have had upper abdominal pain, loss of appetite and frequent loose bowel movements that are smaller than usual. I'm terrified I have bowel cancer, I do occasionally still get blood but haven't for a while.
I also have a lump in my neck and have lost some weight so I was terrified I had lymphoma but the doctor said it was 'just a lymph node'
This is ruining my life, I just want to cry all the time and feel like I can't look after my 1 year old properly.

From what you describe it seems much more likely you have IBS, lots of people write about it here so it seems very common. It's very sad that your friend and your cousin has come down with bowel cancer. What you could perhaps do is to do a full health test once every few years, including testing for bowel cancer, and go to your mammography tests and cervical screening tests. The blood could be anything from IBS to haemorrhoids. It's a little bit costly to go and do a health checkup, but it can put your mind at ease. I do it but I'm much, much older, I didn't do anything when I was your age, no tests, nothing.

I didn't want to read and run. It sounds like you have a health anxiety, understandable given your circumstances. Have you had bloods done? It's very hard, but try to place trust in your GP - they're the experts. Anxiety can manifest itself very physically - there are lots of threads on Mumsnet about it. Perhaps return to your GP for further tests but also highlight your anxious feelings too. Some people take meds/have CBT and these are very effective.

I have been able to put it down to IBS for a long time but since finding out about my cousin I have had this constant pain in my stomach and these strange bowel movements so of course I've googled and it says change in bowel movements and pain can be a symptom. Can you get full health checks on the NHS?

This year alone my grandad had been diagnosed with terminal prostate cancer spread to his spine, we had just started to get our heads around that and then my cousin was diagnosed and shes only 1 year older than me and basically shes going to die.. they just can't say when.
Thank you MrsPatmore - do you think this sounds more like anxiety than anything sinister? I had a full blood count done a couple of weeks ago and it was clear, but then of course I look on google and it says that cancer doesn't always show on blood tests. I'm going to the doctor on Saturday and I think I might get my mum to come with me to help get across how I've been feeling. Its just with this stomach pain and the fact I've lost a bit of weight I'm just obsessed that there must be something wrong with me :-(

Didn't you post about this last week?

Speak to your GP about health anxiety.

I posted about the lump in my neck last week and being scared about having lymphoma :-( Now I'm still scared about that along with whatever is wrong with my stomach and bowel cancer. I'm just so fed up. I already take Citalopram
