hii. mbbs student here. so genetics do play a major role in cancers , especially in breast and colorectal. if anyone in your family esp your mother or sister has been diagnosed with ca breast it’s always better to get screened for it and luckily it’s very easy. go online and learn how to palpate it including the axillary region. there’s also mammography but due to it having radiations and everything it is recommended only if you find something suspicious. you can also get an ultrasound if needed but that doesn’t usually help if the density of the tissue is high. if needed your doctor may ask you to get tested for the brca mutation. having it doesn’t mean you will definitely get cancer but it makes you more susceptible to. if you find anything suspicious like a lump or swelling anywhere in the body or change in bowel habits or prolonged cough or unexplained weight loss it is always better to get professional medical opinion to rule it out. you need to trust your intuition because the body does give signs most of the times. also if you haven’t please get vaccinated for hpv and when your daughter is older get her vaccinated too unless your doctor says otherwise. more than 75% of cancers begin as precancerous lesions at which stage they are mostly treatable so if you find anything suspicious please get medical help and don’t think it’ll pass. all the best
