Doctors have identified several kinds of breast cancers. This is not to mention the many cases in which a tumor in the breast is nothing more than a cyst or a harmless benign lump (ACS, online). The majority of breast cancers, almost 95% are cancer tumors that develop in the milk ducts. Those cancers which remain inside the duct without spreading out are known as cancers. On the other hand, if the cancer cells spread out and invade other areas, they are known as invasive cancers. The other types of breast cancer, almost 5%, are known as lobular breast cancers because they develop in the breast lobes. A very rare type of cancer occurring in only 1% of all cases is known as inflammatory breast cancer. In inflammatory cases, the cancer cells spread very fast and invade other cells, but it can be identified very easily because it blocks the lymph vessels and the channels in the skin, turning the breast into a hard and warm surface with a clear red color (ACS, online).

According to established rules, a subsample (28%) of dubious cases of death among breast cancer cases were selected for blinded review with two observers. If there had been a true effect of screening, with a 24% reduction of breast cancer mortality after 18 years as reported among the cases potentially eligible for the review, one would have expected 24% fewer dubious cases to be selected for review from the study group than from the control group. This was not so as 71 versus 73 cases were selected. We therefore wrote that the review appears to be biased since more deaths were classified as caused by breast cancer in the control group than in the screened group.2,4 Based on the classification in the control group, there were 21 fewer cases than expected which were classified as breast cancer deaths in the study group (P = 0.0003). FPR find our calculation ‘a little hazy’ although they used the same numbers as we did, 13 of 71 versus 35 of 73, which gives P = 0.0003 with Fisher's exact test.
