Question Answered step-by-step 6. Michelle is a health promoter who is passionate about the… 6. Michelle is a health promoter who is passionate about the prevention of breast cancer. She believes that the best way to address the growing incidence of breast cancer is through early detection efforts. Her rationale is that patients whose breast cancer is detected earlier tend to have a higher 5-year survival rate. What is the pathophysiology behind this?a. Patients with stage II and III breast cancer tend to be asymptomatic, but once they have reached this stage, their cancer is resistant to most forms of treatment including chemotherapy, radiation, and hormonal therapy.b. Cases of breast cancer that have been caught through early detection tend to be in the earlier stages, and thus the tumour has not breached the basement membrane yet or is still relatively confined to the area.c. Cancer Care Ontario does not recommend breast screening in women under the age of 50 because there is limited evidence to suggest that this practice leads to improved survival.d. Diagnosing patients with late-stage breast cancer is more difficult than diagnosing early-stage breast cancer because it requires a microscopic evaluation by a pathologist to assess size, anatomic location, growth, and spread.e. Excess stimulation of the epithelial cells lining the ductal and glandular structures, particularly by estrogen, stimulates cell proliferation.  Science Health Science HLTC 19 Share QuestionEmailCopy link Comments (0)
