The medication has gained world recognition within a very short span of time, now it is widely used by female for the prevention of many forms of breast cancer. The medication is so popular; the generic version named generic Tamoxifen has also come in the market. Generic Tamoxifen is also formulated by using the active ingredients used in the formulation of brand name medication known as Nolvadex. In fact the medication is known for its successful results, but you are advised to buy Tamoxifen as per your doctor’s recommendation. It is available in different dosages at the prices one can afford easily. This is the main reason, it is also known as the cheap Tamoxifen. When it comes to buy Tamoxifen, you can buy it from both the online and offline market. In other words, because of its popularity and wide use, the marketplaces are flourished with Tamoxifen. One can buy it easily by placing an order online. In fact, doctors’ prescription is the vital requirement for this medication. Like other medications, it may also cause to some common side effects.

Some of the common side effects like bone pain, hot flashes, tiredness, muscle pain, vaginal discharge, weight loss, nausea, muscle pain, etc. In fact, these are the common side effects that last for a very short time and disappear automatically. If you feel signs of any of the side effect for some more time, you are advised to stop using the medication and consult your doctor as soon as possible. Apart from this, it is also important to tell the doctor about your previous and present medical history before using the medication.

Tamoxifen is orally administered just like other hormones. Aside from rendering breast cancer cells into apoptosis, it also acts like estrogen on other tissues and has a positive effect on bone metabolism. Tamoxifen, in comparison to estrogen, stimulates the uterine lining more and both substances are equally effective in retaining bone calcium.

Several studies have shown that Tamoxifen increases the cure rate of women with non-invasive breast cancer, but is still controversial in its clinical use. The controversy lies on a recent clinical trial, which aimed to determine if Tamoxifen was effective in primary breast cancer prophylaxis in high risk asymptomatic women. At the end of the trial, Tamoxifen was dealt with severe scrutiny and a large amount of negative press overstating its potential adverse effects for asymptomatic women. There is, indeed, no question that Tamoxifen is an extremely potent drug in the treatment of breast cancer patients. Based on the results of another clinical trial involving the use of Tamoxifen, treatment duration plays a significant role in drug treatment outcome. This clinical trial compared five years versus ten years of using Tamoxifen after the diagnosis of breast cancer. The trial showed that five years of taking Tamoxifen significantly diminished the systemic recurrence of breast cancer. On the other hand, an additional five years added only expense and potential risk of uterus cancer with no additional benefits in cure rate. Not all breast cancers, however, respond to Tamoxifen treatment. Response rate to Tamoxifen varies upon the abundance of estrogen and progesterone receptors in the primary cancer.

Since breast cancers are very heterogeneous, they do not develop in the same cellular way. About 60 percent of breast cancers contain estrogen and progesterone receptors, while others contain less. Tamoxifen appears to be more effective in women who have more of these hormone receptors in their tumors than those who do not. On the other hand, within a given breast cancer, there may be cells that have more hormone receptors than others do. Hence, the effect of Tamoxifen on these conditions varies. It is also possible that over time, breast cancer cells that are hormone receptor positive may evolve and may not contain hormone receptors anymore. This may explain why women who receive a combination treatment of Tamoxifen and chemotherapy may have a better response to treatment than with either therapy given alone. In most cases, when chemotherapy and Tamoxifen are given in a cancer patient, they are given sequentially; initially, chemotherapy is given to destroy hormone receptor negative breast cancer cells and then followed by Tamoxifen, which can then act on hormone receptor positive cells that may be less susceptible to chemotherapeutic drugs.

In a few cases, perimenopausal women seem to have a difficulty with Tamoxifen use. Most premenopausal women in their 30s and 40s almost have no adverse effects with Tamoxifen and older women who are not in hormone replacement have little problem with Tamoxifen treatment.

The major side effect of Tamoxifen is uterine toxicity. Some women taking the drug have endometrial thickening, a stimulation of the glandular lining of the uterus, which can become cancerous if left unnoticed. The chance of developing uterine cancer as a result of Tamoxifen use is quite small, only about one percent. Nevertheless, the uterus must be monitored carefully with either an ultrasound or endometrial biopsy during the patient’s annual pelvic examination if she is taking this drug.
