None of this is professional medical advice, but I'm just giving you my opinion.
Stop worrying. It's unlikely it's cancer. Basic blood tests would almost certainly show something seriously wrong with any gi cancer that is that advanced and causing symptoms like that. Your blood work would most likely be an absolute mess if you have advanced cancer with cachexia(weight loss from cancer). Liver panel, pancreatic enzymes ect. would most likely be a disaster if you had advanced pancreatic cancer as an example and you'd often present with jaundice since the bile duct gets blocked from the tumor. Your skin isn't yellow, right?
You're also at very low risk at your age of colorectal cancer or really any GI cancer for that matter.
All that being said, you are having concerning symptoms so see a doctor and have them figure it out. They can do an ultrasound, endoscopy, colonoscopy ect.
You would think that but not at all. I looked back on my old blood tests and all seemed good except a higher than average cholesterol level. Most do not have a liver panel at all and I even went to check, they do the bare basics. For some of these cancers you have to look for like CA19 levels or whatever and specifically for tests for that very thing.
However, I have Googled and Reddited my symptoms a lot and it seems like every other 30-something on reddit gets diagnosed with some kind of Cancer meant for people in their 60s. Crazy world we live in.
I have had a lot of strange symptoms such as:
1. Tingling feelings in extremities.
2. Fingers turning somewhat bluer than I am used to.
3. Not being able to sleep some nights because I feel a pain or something on the back of my left eye.
4. Frequent urination, at times getting up often to pee.
5. Pain on the flanks of the stomach that is acute but comes and goes a couple of times a day.
6. A lump/enlarged spleen which I felt (could have been that but it was below the left rib cage).
7. Occasional pain in the shins or my right feet as if it is a nerve or something or bone related, like I have arthritis or something.
8. Pain that is acute but somewhat sharp in center of stomach that comes and goes.
9. Nausea that happens on some nights, had it for a week during Thanksgiving at one point.
10. Feeling like I fade sometimes and can faint but that just happened in the past 2 days if anything.
11. Blurry vision now when I look at a computer screen late at night.
Like either I have extreme anxiety from the stress of life or whatever. My h3ll is that health insurance does not kick in until January and I have to brave it out. It is that wait and helplessness that is killing me. Urgent care has been utterly useless and anything else would cost a fortune. Somehow, my Christmas miracle is going to be that I do not have an emergency before January 1st or else I go into debt.
It is that helplessness, knowing that something in me is not right but not being able to see a real doctor until more than a week out that is just killing me. I am trying to pass my time through whatever way I can because somehow, I need this year to end ASAP so I don't end up in huge debt over a medical emergency.
