Final answer:
Breast self-examination, mammography, and ultrasound are all important techniques in the detection of breast cancer.
Step-by-step explanation:
The statement is True. Breast self-examination, mammography, and ultrasound are all important techniques in the detection of breast cancer. Breast self-examination involves checking the breasts for any changes or abnormalities such as lumps or changes in size or shape. Mammography is an x-ray examination of the breasts and can detect small lumps or abnormalities that may be difficult to feel. Ultrasound uses sound waves to create images of the breast tissue and can help distinguish between solid and fluid-filled lumps.
