I had colon cancer at the age of 38. My brother died at 32 of it. I have a really weird genetic disorder called Lynch syndrome, and it causes certain cancers, colon cancer being the most common but it also causes stomach cancer, uterine cancer and women, brain cancer. Lung cancer isn't one of them. So all this time I've been watched like a hawk for Cancers and getting my blood drawn every year, and having endoscopies and sigmoidoscopy. Another alarming thing with this whole thing is that somewhere in the last 6 weeks I've lost 3 l of blood. My blood levels went from 12 to 9. My cancer doctor is not in but the doctor that's on call from ordered me to get an ferritin and iron binding test done tomorrow. I also have a scheduled ultrasound on my kidney, this is before all this happened and I'm having a mammogram done tomorrow. These are all just things I do every year. But the blood losses alarming because either I'm not making enough or I've lost it somewhere or I'm losing it somewhere I should say. They want to figure out what's going on that's why they're doing this test. On the 18th I have an endoscopy and sigmoidoscopy scheduled. So this is going to be one doctor appointment after the next for the next month!
