Final answer:
Risk factors such as nulliparity, early menarche, late menopause, and hormone replacement therapy are associated with an increased risk of breast cancer. These factors relate to prolonged estrogen exposure, which promotes the growth of estrogen-sensitive tissues.
Step-by-step explanation:
The risk factors of nulliparity, early menarche, late menopause, and hormone replacement therapy (HRT) are associated with an increased risk of developing breast cancer. These risk factors are related to prolonged exposure to estrogen, which can lead to the growth of estrogen-sensitive tissues, increasing the risk of cancer in such tissues. While HRT can help reduce menopausal symptoms like hot flashes, night sweats, and vagainal drynes, and prevent osteoporosis, its use has been associated with increased risks of several conditions including stroke, heart attack, blood clots, and various types of cancer including breast, ovarian, and endometrial cancer. On the other hand, risk factors for cervical cancer include unprotected sex, multiple sexual partners, early sexual activity, not receiving the HPV vaccine, a compromised immune system, and smoking, which are distinct from those associated with breast cancer.
