I was also told that it takes about 10 years from when a cancer cell starts to divide until it is visible on a mammogram reading.
That may be the case for a minority of breast cancers but it is a VERY MISLEADING thing to say. If this were the case why is the national screening programme set at 3 yearly intervals? Surely 10 yearly would be sufficient (perish the thought).
My following comments won't surprise anyone who has read my previous posts...
Personally I wish that routine mammograms were available in UK from a younger age and with more frequency, as is the case in some other countries. That way, my large multifocal grade 3 cancerous mass would have been detected way before it was palpable by me (at the age of 47). Then maybe I would be sitting here with two breasts instead of one and a whole load more lymph nodes, maybe I would not then have had to undergo chemotherapy, radiotherapy and endocrine therapy in order to stay alive.
For those of you who are wavering because of the discomfort of the actual mammography procedure, let me assure you that disfiguring surgery and other cancer treatments are a lot more uncomfortable.
The exposure to radiation with each mammogram is roughly similar to flying in an airliner for a few hours.
http://www.breastcancercare.org.uk/node/1154051If DCIS is detected, a person can make a decision with what treatment to proceed. Oncologists make recommendations, patients decide whether to consent to treatment. When all is said and done, DCIS is a carcinoma, it is
not pre-cancerous. If left, by the time that person returns for a mammogram 3 years later, depending on the grade, it could have become an invasive cancer which may or may not have metastasised beyond the breast.

I think it's probably pretty clear which side of the fence I am on! That said, if someone chooses to opt out of mammography and/or self examination, I accept that they make that choice. For those who are interested, IMHO the Breast Cancer Care website is an excellent source of information.
