can scratching a mole and making it bleed cause it to become cancerous?

No: Scratching a mole will not transform it into a melanoma (cancer). Of course, if it already is melanoma and you scratch it, you can make it bleed but it was not the scratching that made malignant. If you have any suspicious lesion on the skin, do yourself a favor and see your doc or better yet a dermatologist. If it's nothing, it will help your anxiety and if it's melanoma, it can save your life.

No: Scratching a mole will not make it become cancer. However, if you were scratching it does it itch? Itching is a concerning symptom that makes doctors more suspicious that a mole could be cancer. Moles are easily removed. It is often an office procedure. Please see your doctor or surgeon to have it evaluated to know for sure if it needs to be removed and tested.
