Breast cancer is the second biggest killer of women next to cervical cancer.

A base line mammogram is recommended after the age of 40 years with regular yearly screening after 40 years of age, especially more so in those with family history of disease. Regular mammography screening helps detect cancer early and thus save many precious lives. It is also advisable prior to HRT (Hormone replacement therapy), in any skin changes, nipple discharge, persistent pain, lump etc. Mammograms and ultra-sound scans are complimentary investigations and help detect lesions that may not be apparent in one investigation. Mammography is however highly sensitive in fatty breasts and is the recommended investigation for screening.
We have latest Philips machine (IU- 22) for sonomammography. It also has latest facility of breast elastography which is very helpful in categorizing breast lesions as benign and malignant. There is a dedicated breast MRI with special breast coils to perform dynamic breast MRI examination.
Thus for breast imaging we have
-Mammography
-latest GE equipment.
-Breast ultrasound (sonomammography).
-Breast elastography. -Breast MRI
