Nid oes un achos o ganser y fron, ond gall sawl ffactor gynyddu'r risg o ddatblygu'r clefyd.
Mae rhai o'r ffactorau hyn yn cynnwys:
1. Oedran: Mae'r risg o ganser y fron yn cynyddu wrth i fenyw fynd yn hŷn.
2. Hanes teuluol: Mae risg i fenyw gael canser y fron yn uwch os oes ganddi berthnasau agos (maer, chwaer, neu ferch) sydd wedi cael canser y fron.
3. Mutasau genetig: Mae rhai mutasau gen etifeddol, fel BRCA1 a BRCA2, yn cynyddu'r risg o ganser y fron.
4. Hanes atgenhedlu: Gall beichiogrwydd cynnar, menopaws hwyr, a peidio â chael plant neu gael y plentyn cyntaf ar ôl 30 oed gynyddu'r risg o ganser y fron.
5. Therapi disodli hormonau: Mae gan fenywod sy'n cymryd therapi disodli hormonau ar gyfer menopaws risg uwch o ganser y fron.
6. Defnydd alcohol: Mae yfed alcohol yn cynyddu'r risg o ganser y fron.
7. Obesity: Mae bod yn orwestr neu'n obes yn cynyddu'r risg o ganser y fron.
8. Di-weithrediad corfforol: Gall ffordd o fyw sy'n eistedd yn cynyddu'r risg o ganser y fron.
9. Amlygiad radiadau: Gall amlygiad i ddosau uchel o radiadau, yn enwedig yn ystod plentyndod, gynyddu'r risg o ganser y fron.
10. Dwysedd y fron: Mae gan fenywod sydd â phennau dwys risg uwch o ganser y fron.
11. Hanes beichiogrwydd: Mae gan fenywod a ddechreuodd beichiogrwydd yn gynnar neu a aeth trwy'r menopaws yn hwyr risg ychydig yn uwch o gael canser y fron.
12. Breastfeeding: Mae gan fenywod nad ydynt erioed wedi breastfeeding risg ychydig yn uwch o ganser y fron.
13. Rheoli geni: Mae gan fenywod sy'n defnyddio contraceptiaid llafar risg ychydig yn uwch o ganser y fron.
Mae'n bwysig nodi nad yw cael un neu fwy o'r ffactorau risg hyn yn golygu y bydd menyw yn datblygu canser y fron yn bendant, ac nid oes gan lawer o fenywod sy'n datblygu canser y fron unrhyw ffactorau risg adnabyddus.
Yn ogystal, ni ellir newid rhai ffactorau risg, fel oedran a hanes teuluol, tra y gellir addasu eraill, fel ffactorau ffordd o fyw, i leihau'r risg.

What causes breast cancer?
There is no single cause of breast cancer, but several factors can increase the risk of developing the disease.
Some of these factors include:
1. Age: The risk of breast cancer increases as a woman gets older.
2. Family history: A woman's risk of breast cancer is higher if she has a close relative (mother, sister, or daughter) who has had breast cancer.
3. Genetic mutations: Certain inherited gene mutations, such as BRCA1 and BRCA2, increase the risk of breast cancer.
4. Reproductive history: Early menstruation, late menopause, and having no children or having the first child after age 30 can increase the risk of breast cancer.
5. Hormone replacement therapy: Women who take hormone replacement therapy for menopause have a higher risk of breast cancer.
6. Alcohol consumption: Drinking alcohol increases the risk of breast cancer.
7. Obesity: Being overweight or obese increases the risk of breast cancer.
8. Physical inactivity: A sedentary lifestyle can increase the risk of breast cancer.
9. Radiation exposure: Exposure to high doses of radiation, particularly during childhood, can increase the risk of breast cancer.
10. Breast density: Women with dense breasts have a higher risk of breast cancer.
11. Menstrual history: Women who started menstruating early or went through menopause late have a slightly higher risk of breast cancer.
12. Breastfeeding: Women who have never breastfed have a slightly higher risk of breast cancer.
13. Birth control: Women who use oral contraceptives have a slightly higher risk of breast cancer.
It is important to note that having one or more of these risk factors does not mean that a woman will definitely develop breast cancer, and many women who develop breast cancer have no known risk factors.
Additionally, some risk factors, such as age and family history, cannot be changed, while others, such as lifestyle factors, can be modified to reduce the risk.
