Two-cancer screening usually refers to breast cancer and cervical cancer. Two-cancer screening is usually used to screen women for breast cancer and cervical cancer, and the common examination items for two-cancer screening mainly include breast ultrasound, human papillomavirus, liquid-based thin-layer cytology, routine gynecological examination and so on. It is recommended that women aged 22 to 64 who are sexually active and have no contraindications can go to the hospital regularly for breast cancer and cervical cancer screening, especially those whose close relatives have a history of cancer, which is conducive to early diagnosis, early detection and early treatment of the disease. For women with no high-risk factors or no abnormalities in screening, they can choose to undergo breast and cervical cancer screening every two to three years.
