Which is why you don't see that many chiropractors on talk shows, although they naturally belong there. >> (The doctor I saw on TV said nothing about a low fat, high fiber diet--which has been show to decrease the risk of breast surgery.<< Actually it hasn't yet-- such a diet has been statistically associated with less change of breast cancer, but that's not quite the same thing. >>Worse yet, I saw a news feature on TV about a woman who, having seen her mother die of breast cancer, chose to have both breasts removed to avoid the same fate, even though there was no indication (other than a speculative hereditary factor) that she would be likely to suffer the same fate. Though I can appreciate her fear (terror, more likely), I have great difficulty understanding a rational surgeon carrying out such wishes, especially given the evidence and abundance of preventative steps.<< The problem is that the "preventative steps" you mention are far more speculative in their effect (which will small even if present) than the surgery is. There is also the fact that (until recently) a woman could have prophylactive surgery, leaving nipple intact (which you cannot do with cancer, often), then reconstructive surgery, and come out looking about the same as before. Crazy, you say? In most cases. But consider the woman who comes from a family which really does have one of the identified breast cancer genes, and has a risk of breast cancer not 10% (which is the average), but more like 50% ? What the woman does there will depend on a lot of tradeoffs which are very personal. It isn't up to the doctor to do any demanding in such a situation, but it's not immoral of a surgeon to operate on such a woman if she wants it done. Or even to tell her that she (for some surgeons ARE women, remember) would have it done if SHE were in those circumstances. Of if a "he," would urge his wife to do it. >I would welcome a Dr.'s comment/opinion as to whether or not removal >of breasts as in the case above reduces the risk for cancer, or merely >precludes a cancer from forming in (nonpresent) breasts... Same thing, is it not? Surely you didn't imagine that operating on one breast reduces cancer risk in the other? Steve Harris, M.D. From: sbharris@ix.netcom.com(Steven B.

A medline search gave me the cite for the editorial, as well as a letter by Zumoff in the same issue (see below). There is strong evidence here for an estrogen threshold effect. For evidence of alcohol's clear influence on breast cancer risk, I've also included some other recent abstracts below. It's a real effect, and happens in experimental animals also. The effect of alcohol consumption on breast cancer risk in studies is far greater than the effect of HRT, and (in fact-- as I now see) the epidemiological effect of HRT does not show up EXCEPT with alcohol consumption (which may explain some of my own personal clinical experiential biases here-- I've already explained that most of my own HRT patients are elderly Mormon women who don't drink, and I really see very little breast cancer). That being the case with the breast cancer causing properties of alcohol, even in very small quantities (5 grams a day is about 2 ounces of wine, not 3, BTW), I suppose that the rage we've seen in this group toward "drug companies," and "drug doctors" will now be poured out, so to speak, upon vintners? Somehow, I doubt it. We're not always talking about rationality here on alt.support.menopause. ... You know, my friends, with what a brave Carouse I made a second marriage in my house Divorced old barren Reason from my Bed And took the Daughter of the Vine to Spouse ... In truth, some of the same tradeoffs between cardiovascular risk and breast cancer risk show up on the question of wine consumption, as they do on hormone consumption. It seems that if you want only to take care of your heart, as an elderly woman you'd best do one or the other, not both.

Nagata C, Kabuto M, Takatsuka N, Shimizu H Department of Public Health, Gifu University School of Medicine, Japan. chisato@cc.gifu-u.ac.jp We measured serum levels of estradiol (E2), sex hormone-binding globulin SHBG), progesterone, and dehydroepiandrosterone sulfate (DHEAS) in 61 postmenopausal women drawn from female residents in a community in Japan to evaluate the relationships between these hormone levels and potential breast cancer risk factors. The information on reproductive history, body size, alcohol use, and physical activity was obtained by means of a self-administered questionnaire. There was a significant trend in increasing E2 level with increasing height after taking account of age and body mass index (BMI) (p for trend = 0.04). BMI was inversely associa- ted with SHBG level after controlling age (p for trend = 0.01). Decreasing progesterone with increasing BMI was observed after controlling age and history of hysterectomy (P = 0.05). Alcohol consumption was positively associated with E2 level and there was a strong linear trend after controlling for age, height, and BMI (p for trend = 0.001). Trend for increasing DHEAS with alcohol consumption was also statistically significant after controlling for age and history of hysterectomy (p for trend = 0.01). Reproductive factors as well as physical activity were not related to any of the hormone levels.

Swanson CA, Coates RJ, Malone KE, Gammon MD, Schoenberg JB, Brogan DJ, McAdams M, Potischman N, Hoover RN, Brinton LA Nutritional Epidemiology Branch, National Cancer Institute, Bethesda, MD 20892-7374, USA. In a population-based case-control study of women younger than 45 years of age, we obtained a detailed lifetime history of alcohol use to evaluate the effects of drinking during different periods of life in relation to breast cancer risk. This analysis focused on interviews obtained from 1,645 cases and 1,497 controls. Breast cancer risk was not influenced by drinking during the teenage years or early adulthood. Contemporary drinking (that is, average intake during the recent 5-year interval) was directly associated with risk, but the adverse effect of recent drinking was restricted to women who consumed > or = 14 drinks per week [relative risk (RR) = 1.7; 95% confidence interval (CI) = 1.2-2.5]. The effect of alcohol was most pronounced among women with advanced disease. Compared with nondrinkers, the risk estimate associated with recent consumption of > or = 14 drinks per week was 2.4 (95% CI = 1.6-3.8) for women with regional/distant disease. Our data add support to the accumulat- ing evidence that alcohol consumption is associated with increa- sed risk of breast cancer and further indicate that alcohol acts at a late stage in breast carcinogenesis.

Singletary K Department of Food Science and Human Nutritior, University of Illinois, Urbana 61801, USA. There is considerable evidence from epidemiological studies to support a positive association between alcohol intake and risk for breast cancer. Yet, experimental evidence has provided less convincing evidence to support this relationship, although much less attention has been focused on elucidating the effect of ethanol on breast carcinogenesis in animal models. Although the number of reports are limited, information on the effect of ethanol on mammary carcinogenesis in spontaneous, chemically induced and metastatic models has been published. In addition, a small number of reports provide insights into an influence of ethanol on the physiological processes associated with the initiation, promotion, and progression stages of breast carcinogenesis in animals, as well as on the growth of human breast cancer cells. This information from the literature is summarized, and specific recommendations put forth so that greater progress can be made in this controversial and complex research area.

I think it's been proven that the classic Halsted radical (with removal of underlying muscle) doesn't do any better than the modified radical (muscle left in place). And for lots of lesions, lumpectomy plus radiation is as good. It's hard to define success rate, as breast cancer is so slow. Probably you have to look at at least 15 year survivals, and perhaps even 20 year survivals. These figures are not available for many of the less disfiguring procedures. Also, the stage of the initial tumor is important. Probably your best bet is to collect more information on this lady. What did she have (how big the tumor, how advanced), what options was she offered, etc. If she had a large tumor going into the muscle, they may well have had no choice but a radical. Some women have progressed so far by the time they seek attention that they can't even do that. I've seen several of these terrible cases.

However, it's possible that the cancer cells are >shaped like tubes. COMMENT: Tubular carcinoma is just a ductal carcinoma that hasn't got going yet, and is only one-cell thick, lining the ducts. So the prognosis is even better. These are epithelial cells lining the milk ducts (which are tubes, you see), that have become cancerous. When they section them, they look to see what fraction of the cells are next to the duct lumen. If it's more than 70% (meaning 70% of the cancer cells are actually lining the duct, 1-cell deep), and the cells are not too screwly looking, you get the good diagnosis of tubular carcinoma. As the fraction of cells which are more than 2 cells "deep" from a duct goes up over 30%, then you have ductal carcinoma. But this still hasn't pentrated the smooth muscle of the ductal wall, and prognosis is a little poorer, but still VERY good. All this is very much like the various grades of cervical cancer, and looks a lot like them. This tubular stuff is like grade I cervical cancer "in situ". Anyway, tell everybody in your family to calm down. If you gotta have breast cancer, this is what you want to have. SBH |
