Answer and explanation:
Cancer screenings are fundamental in the process of diagnosing cancer at an early point (sometimes even before symptoms appear) which can directly impact the prognosis of the patient.
Both Mr. and Mrs. Brown, being above 60 years of age, should get screened for several cancers. Two very common and death-threatening cancers that can appear at their age regardless of the patient's sex are Lung cancer and Colorectal cancer. Lung cancer screening is usually done through a low-dose CT scan and is a strongly suggested screen test if the patient is or was a heavy smoker since tabaquism highly increases the risk of lung cancer (among other cancers as well). Colorectal cancer can be screened through a colonoscopy, which is a test that consists of the endoscopic examination of the rectum, the colon, and the distal part of the small intestine.
Mr. Brown, who is a male, should also get checked for Prostate cancer through a Prostate-specific antigen (PSA) blood test which, if found abnormal, should be followed by a prostate biopsy.
Mrs. Brown, a female, should get screened for two additional very common cancers in women: Breast Cancer and Cervical cancer. Breast cancer can be screened through mammograms, and Cervical cancer can be diagnosed through either an HPV test or a Pap test.
It is also important to remind both patients that these screenings should be repeated every year.
