Tað er ikki nøkur einastøðug orsøk til bróstkrabba, men fleiri viðurskifti kunnu økja um vandan fyri at fáa sjúkuna.
Nakrir av hesum faktorum eru:
1. Aldur: Vandin fyri at fáa bróstkrabba økist, sum kvinnan verður eldri.
2. Familjusøga: Kvinnur eru í størri vanda fyri at fáa bróstkrabba, um tær hava eina nærmastu skyld (móðir, systur ella dóttur), sum hevur havt bróstkrabba.
3. Genbroytingar: Ávísar arvaligar genbroytingar, sum til dømis BRCA1 og BRCA2, økja um vandan fyri at fáa bróstkrabba.
4. Forteljingarsøga: At fáa tíðliga menstruatión, sein skiftisár og ikki at fáa børn ella at fáa fyrsta barnið eftir 30 ára aldur kann økja um vandan fyri at fáa bróstkrabba.
5. Hormonviðgerð: Kvinnur, sum fáa hormonviðgerð í skiftisárunum, eru í størri vanda fyri at fáa bróstkrabba.
6. Alkoholnýtsla: Alkoholnýtsla økir um vandan fyri at fáa bróstkrabba.
7. Ovurfita: At vera ov tjúkkur ella feitur veksur um vandan fyri at fáa bróstkrabba.
8. At vera kropsliga óvirkin: At sita stillur kann økja um vandan fyri at fáa bróstkrabba.
9. Strálulýsing: Tá ið ein verður útsettur fyri stórari geisling, serliga í barnaárunum, kann tað økja um vandan fyri at fáa bróstkrabba.
10. Brjósttættleiki: Kvinnur við tættum bróstum eru í størri vanda fyri at fáa bróstkrabba.
11. Menstruatión: Kvinnur, sum tíðliga fáa menstruatión ella seinni eru komnar í skiftisárini, eru í eitt sindur størri vanda fyri at fáa bróstkrabba.
12. Bróstageving: Kvinnur, sum ongantíð hava givið bróst, eru í eitt sindur størri vanda fyri at fáa bróstkrabba.
13. Fosturtøkufyribyrging: Kvinnur, sum taka fosturtøkufyribyrgjandi heilivág, eru í eitt sindur størri vanda fyri at fáa bróstkrabba.
Tað er týdningarmikið at leggja til merkis, at tað ikki er vist, at ein kvinna fær bróstkrabba, um hon hevur ein ella fleiri av hesum vandastøðum, og nógvar kvinnur, sum fáa bróstkrabba, hava ongar kendar vandastøður.
Summir vandatættir, sum til dømis aldur og familjusøga, kunnu ikki broytast, meðan aðrir, sum til dømis lívsstíllur, kunnu broytast fyri at minka um vandan.

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.
