Ask The Doctor: Living With Prostate Cancer [Video]

Though prostate cancer is the second most common cause of cancer death in men, most men with prostate cancer do not die of the disease. The prostate is only essential for fertility, and for most men, when they are diagnosed, fertility is no longer a concern. Many men are on active surveillance without immediate treatment of their cancer, and they need close monitoring with examinations, PSA testing, MRIs, and repeat biopsies as determined by their healthcare provider. Men who have undergone curative treatment need routine visits to monitor PSA for cancer recurrence and to manage any complications of the treatments. Afterinitial recovery from surgery or radiation, a man can resume all pre-treatment physical activities. If there are problems with leakage or erectile dysfunction, there are medications, exercises and procedures to get back to your life and daily activities. Men might also want to consider joining a cancer support group.Learn more at zerocancer.org.

Painful bone metastases are common in advanced prostate cancer. Physicians often order treatment with strontium- 89left({ }^{89} mathrm{Sr}right), a radionuclide with a strong affinity for bone tissue. A patient is given a sample containing 4 mathrm{mCi} of { }^{89} mathrm{Sr}. a. If 20 % of the { }^{89} mathrm{Sr} remains in the body after 90 days, write a function of the form Q(t)=Q_{0} e^{-k t} to model the amount Q(t) of radioactivity in the body t days after the initial dose. b. What is the biological half-life of { }^{89} mathrm{Sr} under this treatment?Watch the full video at:https://www.numerade.com/questions/painful-bone-metastases-are-common-in-advanced-prostate-cancer-physicians-often-order-treatment-with/Never get lost on homework again.
