If you or a loved has been diagnosed with breast cancer you know it can be a very confusing moment; after the initial shock a treatment must be chosen. In the advances to find a cure for breast cancer a wide range of treatment options are offered and among them is drug therapy. Women and their physicians opt for drug therapy as it is effective in treating cancer cells that have spread and is non-invasive. Picking your treatment therapy will take a lot of careful thought as it will not be the same for every woman. A plan must be chosen depending on your unique situation as cancer medications are not cheap. No matter which treatment method is chosen oral cancer prescription drugs are always part of the combination.

Once your doctor prescribed the right combination of treatments you have to understand your prescription. I will discuss 3 different drugs that are widely prescribed to treat breast cancer and prevent recurrence. The first drug is:

•Tamoxifen aka Nolvadex is a drug categorized as antineoplastics; it works by blocking the effects of estrogen in the body which is required for cancer cells to grow. This medication is known to be an anti-estrogen medication. The chemical drug Tamoxifen was discovered by Astra Zeneca and is among the first breast cancer medications to be created. There is no patent over Nolvadex anymore therefore you can buy generic Tamoxifen.

•Anastrozole aka Arimidex is also a drug known as an antineoplastic but unlike Tamoxifen it activates an enzyme know at aromatase. Anastrozole is a non-steroidal aromatase inhibitor which cuts off the supply of estrogen that cancer cells need to grow and survive. Anastrozole was also created by Astra Zeneca and is sold under the brand Arimidex. The patent over Arimidex expires in 2010 in the US but generic Arimidex is available in Canadian pharmacies as Anastrozole.

•Letrozole aka Femara is also a non-steroidal aromatase inhibitor that works but this medication is used after surgery has been performed. Unlike Tamoxifen and Anastrozole, this medication is used to treat advanced breast cancer in postmenopausal women. Also Femara reduces the risk of breast cancer recurrence in women who have been treated for early-stage breast cancer with Tamoxifen for 5 years. Generic Femara is available in Online Canadian Pharmacies but not in US pharmacies.

The cost of treating breast cancer in the US is enormous; for example, the retail price of Femara is approximately $1,015 monthly. For that reason many women are researching cheaper alternatives for filling their prescriptions. Luckily generic cancer medications from Canada are available. If you do your research thoroughly you can find a fully licensed Canadian Online Pharmacy to fill your prescription safely and affordably.
