Dans le cadre du mois d’octobre rose « CHANGEONS LA CONVERSATION : 31 VRAIES INFORMATIONS » avec la National Breast Cancer Coalition. Suivez le lien et vous trouverez 31 affirmations très intéressantes, je vous en colle quelques-unes ci-dessous. Hélas elle sont en anglais, mais un site que vous pouvez voir dans mon billet Deux trouvailles (http://wp.me/p2efxX-fC) a commencé à en traduire quelques-unes.
Truth #19: Mammography is not prevention. Getting regular mammograms does not prevent you from getting breast cancer.
Mammography is a screening test to detect cancer already present in the breast. It does not prevent cancer, nor will it definitively detect the disease. Continuing with mammography screening is a personal choice, but it does not determine what causes breast cancer, nor will it cure the disease.
Truth #20: Five year breast cancer survival rates do not give an accurate picture of progress against breast cancer.
Because breast cancer takes many years, sometimes even decades, to develop and spread throughout the body, breast cancer survival statistics, particularly five-year survival data, do not accurately portray the impact of breast cancer, or the progress or lack of progress over time. Only mortality rates can give an accurate picture of the impact of the disease since it can measure death rate in the population over a lifetime.
It is often repeated that 98% of women with early stage breast cancer are alive at five years after diagnosis. However, an estimated 20% to 30% of women will have a recurrence of their disease, and may go on to die of the disease, but are included as survivors in these five-year survival statistics. We still do not know how to prevent recurrence and metastasis for most women or how many of the women reported to have survived five years will go on to have a recurrence.
In addition, survival statistics are skewed by screening programs. The more screening there is, the more breast cancers are found. But it does not follow that more lives are saved. Because breast cancer can be slow-growing, finding breast cancer through screening mammography often increases the time women know they have breast cancer, but may not have any impact on final outcomes. Again, following trends in breast cancer mortality rates, rather than survival at five years after diagnosis, is the only way to get an accurate picture of the toll of breast cancer and progress made.
Truth #23: We will not see a significant decrease in breast cancer mortality without a better understanding of breast cancer metastasis.
Women do not die of primary breast cancer. Over 90% of breast cancer deaths are due to the spread of the disease to other organs, such as bone, lungs, and brain.
Approximately 155,000 women are living with metastatic breast cancer in the United States and this is projected to rise to 162,000 by the end of 2011, according to one expert. Close to one-third of the women considered « cured » of breast cancer will suffer recurrences and metastatic spread of the disease, often many years after their initial diagnosis. While researchers have identified treatments that sometimes shrink or slow metastatic tumors, such as estrogen blockers, radiation and chemotherapy, they are most often temporary. Treatments to eradicate metastasis do not exist.
