Question

which of the following increases the chance of developing breast cancer? increased time between puberty and menopause decreased time between birth and puberty decreased time between puberty and menopause increased time between birth and puberty

Explanation:

• Breast cancer risk is influenced by hormonal exposure.
• A longer time between puberty (when estrogen exposure starts) and menopause (when it largely ends) means more cumulative estrogen exposure.
• Estrogen can promote the growth of breast cells, and increased exposure over time can raise the chance of genetic mutations in breast cells that lead to cancer.
• The time between birth and puberty has less direct impact on breast cancer risk related to hormonal exposure for breast tissue as breast - related hormonal changes mainly start at puberty. A decreased time between puberty and menopause would mean less estrogen exposure (lower risk), and a decreased time between birth and puberty also doesn't directly translate to increased breast - cancer - relevant hormonal exposure.

Answer:

increased time between puberty and menopause
