How do you check for breast cancer, and what’s the earliest age you can get it? I’m fifteen… help?
Interesting and sensible questions!1) Increased chances doesnt mean double! It could be that one factor increases your chance of something by 10% and another factor increases it by 5%! Even if you have both factors together, your chances are still only increased by 15%! Although sometimes its more complicated than that and having both factors changes your risk in a different way, by acting syngeneically (ie the total is more than the sum of the parts, e!g! 25%) or to a lesser degree, where the total is less than the sum of the parts, but still more than either one alone (e!g! 12%) I dont know what the exact case is for the two risk factors you mention!2) Having a baby alters your hormones significantly! Your breasts are doing what they were designed for – making milk to feed a baby! Even if you dont actually breastfeed they still go through the process of getting ready to make milk! Breastfeeding for 12+ months over your lifetime (could be 6 months each with 2 babies) reduces your breast cancer risk too! Also, while you are pregnant and breast feeding you dont have periods! So your body does not have the regular cycle of hormonal changes!3) Yes it could be a decrease in size! Tumours can regress (shrink) naturally in response to changes in your body, or if your immune system starts to attack the tumour! Breast cancers in particular are often sensitive to oestrogen, so as the level of oestrogen rises and falls with your monthly cycle, it is possible that the tumour could grow and shrink! Shrinking could also be a bad sign – that the tumour is breaking up and parts of it are migrating through your bloodstream! This is called metastasis, but it usually occurs at the single-cell level and not in big enough chunks that you would feel a difference!
Improve. The youngest case of breast cancer recorded, was only 15, but I must stress that this is a extremely rare case. Only 3% of women have breast cancer under the age of 40. When did people discover that males can get breast cancer.
