UTERINE CANCER (CANCER OF UTERUS)
Uterine cancer is a type of cancer that begins in the uterus in its lining called the endometrium. Hence also named as endometrial carcinoma.

? Clinical examination
? Transvaginal sonography (TVS) to know endometrial thickness or irregularity.
? MRI pelvis can be done for more details

OVARIAN CANCER
Ovarian cancer constitutes 15-20 percent of all genital cancers. 85-90 percent of all cancers are epithelial in origin. Germ cell constitutes 5-7 percent.

? Blood test like CA125 which is found raised in ovarian cancer.
? CT Scan /MRI to know spread of cancer

Treatment:
Early diagnosis and treatment carry good prognosis.

COLORECTAL Cancer
