Just fat or a cancer lump? (picture)

I've seen it quite a lot on here. People post about fear around weight loss and in their post hidden away somewhere is something like, "I started a diet in January and have given up junk food" yet they still worry about their intentional weight loss. As FMP says above it's irrational, but yes - if you search weight loss on here there are loads of them. None of them turned out to be anything sinister.

I worry about weight loss even when it's on purpose, when I try to lose weight, apparently I can lose weight quite fast ( I do gain fast too though...) But whenever my family are saying that i'm losing weight and that I lose it fast, I start to worry about it and start thinking it's one of the symptoms of cancer.
When I try to lose weight and fully go for it, i'm feeling good and motivated. Once i'm being told I lose it fast, I start to worry about it being a symptom of cancer. I eat again then to see if I gain weight instead of losing. It's a repeatable circle..
