    Tamoxifen progesterone


    Some types of breast cancer are affected by hormones in the blood. ER-positive and PR-positive breast cancer cells have receptors (proteins) that attach to estrogen, which helps them grow. There are different ways to stop estrogen from attaching to these receptors. Hormone therapy is a form of systemic therapy, meaning it reaches cancer cells almost anywhere in the body and not just in the breast. It's recommended for women with hormone receptor-positive (ER-positive and/or PR-positive) breast cancers, and it does not help women whose tumors are hormone receptor-negative (both ER- and PR-negative). Hormone therapy is often used after surgery (as adjuvant therapy) to help reduce the risk of the cancer coming back. Sometimes it is started before surgery (as neoadjuvant therapy) as well. Hormone therapy can also be used to treat cancer that has come back after treatment or that has spread to other parts of the body. Tamoxifen ist ein selektiver Estrogenrezeptormodulator, der als Arzneistoff zur Therapie von Brustkrebs bei Frauen vor der Menopause eingesetzt wird. Tamoxifen wurde von ICI Pharmaceuticals (jetzt Astra Zeneca) entwickelt und bewirkt eine kompetitive Hemmung von Estrogenrezeptoren sowie eine Stimulation von Progesteronrezeptoren. Als „Vater“ der Brustkrebs-Behandlung mit Tamoxifen gilt V. Auch zur Therapie von fibrozystischen Brüsten wurde bei Frauen Tamoxifen angewendet, um Knoten, Schwellungen und Schmerzen zu reduzieren. Forscher der Universität San Diego sollen 2018 herausgefunden haben, dass Tamoxifen gegen die Amöbe Naegleria fowleri wirken soll. Diese löst bei Menschen die in bis zu 95 % der Fälle tödlich verlaufende Primäre Amöben-Meningoencephalitis aus. Als Hormonrezeptormodulator kann Tamoxifen potenziell die Wirkung anderer Hormonpräparate beeinflussen. Insbesondere bei gleichzeitiger Einnahme von Estrogenen mit Tamoxifen kann eine wechselseitige Wirkungsabschwächung beobachtet werden.

    Been on Natpro for about a month and, to be honest, have not seen any improvements. I noted in one of your replies that Natpro activates the oestrogen receptors, but as I am taking Tamoxifen for hormone related breast cancer I wondered if it is safe for me to continue with Natpro - as you are probably aware, Tamoxifen is an oestrogen blocker, but thinking of coming off it due to bad side effects ie. I was hoping Natpro would help with these, but not so far. I wonder if you are taking enough progesterone to work through the oestrogen dominance? There is a natural product out there that is supposed to help with excess estrogen. Hi Anne One month is too soon, it normally takes between 3-6 months to have any real affect. Yes, progesterone does initially activate the oestrogen receptor sites, it has a stimulatory affect followed by a calming affect. As you don't mention having had any symptoms of excess oestrogen from using it, I doubt if it will now. For more info on this please see our page on Oestrogen Dominance. But it will have to work against the against Tamoxifen which is an oestrogen, albeit a mild one, about 1000 times weaker than oestradiol. But nevertheless an oestrogen, so it does increase the risk of endometrial cancer and more because of this. It doesn't surprise me you are having adverse symptoms taking it. Es ist fast schon ein wenig Glück im Unglück, wenn eine Patientin erfährt, dass ihr Brustkrebs „hormonabhängig“ ist. Denn das bedeutet, dass die wuchernden Zellen gestoppt werden können, wenn ihnen ihre „Droge“ entzogen wird – zum Beispiel, indem Hormone wie Östrogen blockiert werden. Jetzt haben Forscher der Universität Cambridge in Tier- und Zellkulturexperimenten entdeckt, dass der therapeutische Erfolg dieser Hormonblockade noch verbessert werden könnte – paradoxerweise mit dem Verabreichen eines Hormons, des Menstruations- und Schwangerschaftshormons Progesteron. Schon lange wissen Forscher und Ärzte, dass manche Typen von Brustkrebs unter dem Einfluss von Hormonen wie Östrogen schneller wachsen. Medikamente wie Tamoxifen blockieren deshalb die Andockstellen für das weibliche Geschlechtshormon. Ob diese „Hormontherapie“ bei einer Patientin nötig und erfolgreich ist, das klären Ärzte vor Therapiebeginn meist über Gewebeproben des Tumors ab. Dabei wird überprüft, ob die Krebszellen viele Andockstellen (Rezeptoren) für Östrogen haben.

    This medication is used to prevent or treat gout attacks (flares). Usually gout symptoms develop suddenly and involve only one or a few joints. The big toe, knee, or ankle joints are most often affected. When uric acid levels in the blood are too high, the uric acid may form hard crystals in your joints. Colchicine works by decreasing swelling and lessening the build up of uric acid crystals that cause pain in the affected joint(s). This medication is also used to prevent attacks of pain in the abdomen, chest, or joints caused by a certain inherited disease (familial Mediterranean fever). It is thought to work by decreasing your body's production of a certain protein (amyloid A) that builds up in people with familial Mediterranean fever. Colchicine is not a pain medication and should not be used to relieve other causes of pain. Buy Colchicine - Your Canada Drug Store - 1-844-416-4282 Buy Colchicine 0.6mg.
