I had 7 ct scans in a month, 5 in a week. roughly 35-42 msv. 5 abdomen, 1 chest, 1 head. the 5 in a week were 3 abdomen, 1 chest, 1 head. i was told because i was small, i didn't really absorb that much radiation. did i raise my risks drastically?

Not drastically, may be a minimal increase over your background risk. You can reduce your risk of cancer by adopting healthy habits: Eat a mostly vegetarian diet, avoid alcohol, tobacco and street drugs, avoid excessive exposure to sun, maintain healthy weight, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is mostly colorless. Wish you good health!
