Shin pain?

My mom looked at me like I was crazy when I mentioned it, but

So, two years ago, my dog randomly started having pains in her leg. 3 vets said arthritis but the pain meds weren’t working and it just kept getting worse. Then her leg turned purple, so we rushed her to the emergency vet, and they did another X-ray and we found out she had bone cancer. It shattered her femur. This happened within just a weeks time.

A couple months later my mom tells me that the couch she has, came with a warning label that the materials have been known to cause cancer.

I’m supposed to go in May to have a bone marrow biopsy done, due to my white blood cells being low (my other levels were fine, no anemia) and i don’t have any infections that I’m aware of.

The past week, my shins have randomly been hurting. I have a toddler and he makes bruises on my legs sometimes (not on purpose ofc) but I only have a light bruise on my leg. I haven’t really changed my routine. Any ideas what could be going on?

I’m terrified I have cancer. 🥺
