    No less, long-term use of tamoxifen ups the risk of getting aggressive cancer in the other breast by 440 percent. In spite of this finding, researchers insist that women should keep taking the drug because, they say, the benefits outweigh the risks. Tamoxifen has been used for over 25 years both to treat breast cancer, as well as to prevent it. Most breast cancers spread when exposed to estrogen, and since tamoxifen inhibits estrogen receptivity, it has been the standard treatment, although recently aromatase inhibitors, a new class of drugs, have taken precedence. Tamoxifen also has frequently been prescribed to high-risk women who don't have breast cancer as a prophylactic measure to stave off tumors. And, it's been used to treat osteoporosis, bipolar disorder, and prostrate cancer. But problems with tamoxifen have been surfacing for years, and now this study shows the drug causes an even more deadly version of the disease it supposedly cures. The tumors negatively associated with tamoxifen use do not feed on estrogen, no drugs on the market have been effective in treating them, and the prognosis for cancers featuring these tumors is worse than for estrogen-dependent cancers. Resistance to tamoxifen therapy in some estrogen receptor positive breast cancers may originate from in utero exposure to endocrine disrupting chemicals, research in animal studies suggests. This study provides a new path forward in human research as about half of the breast cancers treated with this common cancer therapy do not respond well, say researchers. An animal study suggests that resistance to tamoxifen therapy in some estrogen receptor positive breast cancers may originate from in utero exposure to endocrine disrupting chemicals. The study provides a new path forward in human research as about half of the breast cancers treated with this common cancer therapy do not respond well, say researchers at the Georgetown Lombardi Comprehensive Cancer Center, who led the multi-institutional research. ), identified four genes that are linked to tamoxifen resistance and poor prognosis of breast cancer, by comparing results obtained in a new animal model, in human breast cancer cells grown in culture, and in publically available datasets collected from thousands of estrogen receptor positive breast cancer patients treated with tamoxifen. "Higher estrogen levels in utero have been known to increase risk of estrogen positive breast cancer in laboratory animals -- and humans -- but it wasn't known until this study that these elevated levels may also be responsible for tamoxifen resistance," says the study's co-lead author, Leena Hilakivi-Clarke, Ph D, a professor of oncology at Georgetown Lombardi.. Researchers further demonstrated that changes in these genes were reversed by adding well-tolerated epigenetic modifying drugs, valproic acid and hydralazine, to tamoxifen therapy regimen.

    According to a study, just published in Cancer Research, long-term use of tamoxifen ups the risk of getting aggressive cancer in the other breast by 440 percent.

    Tamoxifen (Nolvadex) has been used for over 40 years to treat hormone-receptor positive early, locally advanced and metastatic breast cancers. Learn about tamoxifen and other hormone therapies for metastatic breast cancer. Hormone receptor-positive breast cancers need estrogen and/or progesterone (female hormones produced in the body) to grow. Tamoxifen attaches to the hormone receptor in the cancer cell, blocking estrogen from attaching to the receptor. This slows or stops the growth of the tumor by preventing the cancer cells from getting the hormones they need to grow. Tamoxifen is a pill taken every day for 5-10 years. For premenopausal women, tamoxifen may be combined with ovarian suppression. The benefits from tamoxifen last long after you stop taking it. For some women with breast cancer, taking adjuvant tamoxifen (Nolvadex®) for 10 years after primary treatment leads to a greater reduction in breast cancer recurrences and deaths than taking the drug for only 5 years, according to the results of a large international clinical trial. The findings from the ATLAS trial—presented at the San Antonio Breast Cancer Symposium (SABCS) and published in on December 5, 2012—are likely to change clinical practice, several researchers said. Nearly 7,000 women with early-stage, estrogen receptor-positive breast cancer were enrolled in the trial between 19. After taking tamoxifen for 5 years, participants were randomly assigned to continue taking tamoxifen for another 5 years or to stop taking it. From 5 to 9 years after the women began tamoxifen therapy, there was little difference in outcomes between the two treatment groups. This finding is consistent with those from other trials of adjuvant tamoxifen therapy, which showed that 5 years of tamoxifen can substantially reduce the risk of the cancer returning and of cancer death in the next few years, what one of the trial investigators, Richard Gray, MSc, of Oxford University, UK, called a "carryover effect." The improved outcomes with longer tamoxifen use emerged only after the 10-year mark, Gray explained during an SABCS press briefing. Among the women who took tamoxifen for 10 years, the risk of breast cancer returning between 10 and 14 years after starting tamoxifen was 25 percent lower than it was among women who took it for 5 years, and the risk of dying from breast cancer was nearly 30 percent lower.

    He started having stomach issues (upset stomach) at the time of taking Azithromycin. His pediatrician asked us to track what he's eating for 1 week. He's eating the same things he did prior to the bronchiolitis but now has upset stomach with or without eating. He was given breathing treatments for 1 week and Azithromycin. We've been to his pediatrician, had blood tests run (nothing abnormal). We've had him on a probiotic for 4 weeks approximately with no changes. Not at all times but about 1/2-3/4 of the day he says his stomach hurts ("feels yucky" his words). Now the pediatrician wants us to track his eating for another 3 weeks. Since it's the same food prior to the sickness, I don't understand how that could have any effect on his stomach. I'm frustrated because I want my son to feel normal again.
