I have a cousin (my oldest uncle's daughter) who was diagnosed with leakeumia in January 2018 when she had just turned 2.

I have another cousin (my youngest uncle's son) who started getting symptoms in August 2018 and doctors kept saying it was very rare for 2 kids in the same family to have the same cancer. He was then diagnosed with leakeumia at age 2 and a half in December 2018.

Thankfully, they're both cancer free now and living normal and fun childhoods. They've had regular checks and everything has been fine thankfully.

I have a lot more younger cousins now and I get frightened when one of them gets ill or has to go to hospital. Even though it is rare for two children in the same family, it happened to mine so I feel like it could happen again to another cousin. I'm also scared of diagnosis being delayed becasue of doctors saying it's rare.

I'm also scared for myself. I've been having rectal bleeding (intermittent but when it happens it's a lot!) and lost weight so was referred to a colorectal specialist. Thankfully they didn't see any sign of cancer and I'm waiting for biopsy results now. I've also had severe (but intermittent) bone pain in my right leg for no reason and will be seen about that next month.

I wasn't that scared about being referred to a colorectal specialist since I know colorectal cancer is more common in elderly people. But now that I've read about bone cancer, I am worried that I could have osteosarcoma or ewing sarcoma as I am a teenager.

I am not really sure what the point of my post is but I am wondering if anyone has gone through anything similar in their family. Is it normal to be worried when cancer is rare in teenagers and children? I feel like I may have health anxiety.
