What is Post-Menopausal Breast Cancer?

Before we discuss Arimidex 1mg Tablets as a treatment option for postmenopausal breast cancer, we must first understand what postmenopausal breast cancer is. Breast cancer is referred to as the rapid and unrestrained growth of cells in the breast tissue and can spread beyond the breasts to other parts of the body. With the increase in age, the probability of developing breast cancer also increases, especially in postmenopausal women.

Normally, the hormone “estrogen” is produced by the ovaries, but after menopause, the ovaries stop producing it. Instead, it is produced in very small quantities by the fat tissue in the breasts. This increases the level of estrogen in the breasts, creating a conducive environment and enhancing the risk of developing breast cancer.

Let’s Understand Arimidex and Its Mechanism

Arimidex is a brand-name, FDA-approved prescription drug with Anastrozole as the active component. It belongs to the drug class known as nonsteroidal aromatase inhibitors. This medication is generally prescribed to women who have stopped menstruating to address various stages of hormone receptor-positive breast cancer and to prevent the recurrence of cancer. Aromatase inhibitors help reduce estrogen levels in the body, which is required by the cancer cells for their growth. Reduced estrogen levels limit the growth of breast cancer cells and tumors, thereby minimizing the risk of further spread.

Doctors also recommend Arimidex when other anti-cancer medications (such as Tamoxifen) do not bring the desired results. Besides this, Arimidex is also recommended to minimize the possibility of the development of breast cancer in women who are more prone to it. Arimidex may also be prescribed for purposes not mentioned above. It is important to note that before you buy Generic Arimidex 1mg for any condition, you must discuss with your doctor the risks associated with the medication. Arimidex 1mg is usually taken once a day with or without food for the duration recommended by the doctor.

Side Effects of Arimidex

Like other anti-cancer medications, Arimidex may also cause side effects ranging from mild to serious. Mild, common side effects usually subside as the body adapts to the medication. However, if they worsen or persist longer, it is important that you consult your healthcare provider. Some of these side effects are as mentioned below:

• Headache, nausea, vomiting

• Pain in the joints and back

• Hypertension, depression

• Sore throat, rashes, swelling in the hands and lower legs

Although rare, Arimidex may cause serious side effects, too. If you come across any of these, you must see your healthcare provider immediately.

Coronary Heart Disease

Arimidex may increase the risk of heart ailments among people with narrowed arteries. Therefore, if you have any kind of heart disease, please let your doctor know.

Impacts Bone Health

 Arimidex lowers estrogen levels, and these reduced levels affect bone health, weakening bones and increasing the risk of bone damage and fracture. Therefore, people with osteoporosis and osteopenia must inform their doctor of the same.

Increased Cholesterol Levels

It is important to get your cholesterol checked regularly while on Arimidex, as it can elevate blood cholesterol.

Why is Arimidex preferred for Therapy in Postmenopausal Breast Cancer?

Increased Suppression of Estrogen

Arimidex is more effective than older treatment options, such as Tamoxifen. Clinical evidence indicates that Arimidex provides greater suppression of the aromatase enzyme, thereby reducing estrogen levels. The reduced estrogen levels help create an environment unfavorable to the growth of cancer cells.

Offers More Efficacy

For a long time, Tamoxifen was the commonly preferred treatment option for postmenopausal breast cancer, but lately studies have shown that Arimidex is more efficient. The drug offers better results in preventing the recurrence of cancer, prevents the cancer from developing in the other breast, and restricts and slows the growth of cancer that has spread to other body parts.

Convenient to Administer

Arimidex 1mg tablets are usually taken orally once daily, which makes administration easier and can be accommodated in one's daily routine, unlike other treatment options that require intravenous administration of the drugs. Besides the brand name, Arimidex is also available as a generic, which offers the same efficacy and safety. So people on a fixed income can opt to buy cheap Arimidex 1mg online and continue their treatment longer without worrying about the cost.

Lesser Side Effects

Anastrozole 1mg causes fewer side effects when treating hormone receptor-positive breast cancer in postmenopausal women, which is why it can be taken for a longer time without causing other diseases. Hence, Arimidex is preferred over other anti-cancer medications.

The Bottom Line

Arimidex 1 mg tablets have become the first-line treatment option for hormone receptor-positive breast cancer, particularly in postmenopausal women, due to their proven effectiveness, ease of administration, and fewer side effects. Arimidex inhibits the aromatase enzyme, which reduces estrogen levels and, in turn, prevents the growth and proliferation of cancer cells with minimal side effects. The drug also minimizes the risk of cancer recurrence and prevents it from spreading elsewhere in the body. Arimidex also reduces the risk of breast cancer development in women experiencing menopause or who are more prone to this deadly disease. Though the medication may cause a few side effects, they can be effectively managed with regular monitoring and adherence to the oncologist’s advice. The medication has offered assurance to millions of women globally with postmenopausal breast cancer. It has increased the survival rate with few adverse effects and, most importantly, has given them hope and improved quality of life.
