Are you aware of breast cancer? Let's talk about it simply.

When we hear the word cancer, we all get a little scared, right? That's normal. But breast cancer is a disease that can be treated very successfully if we are properly informed about it and if it is detected early. Although it is most common among women, it can also develop in men to a very small extent. So today, let's put aside our fears about this and learn about it in a very simple way, as if we were talking to a friend.

Simply put, what is breast cancer?

Our bodies are made up of millions of tiny cells. These cells grow, divide, and grow according to a set of rules, and then die when we get older. But sometimes this rule breaks down, and some cells in the breast start to divide rapidly and uncontrollably. This clump of cells is called a tumor .

Not all of these tumors are cancerous. Some are benign tumors. However, when these cells divide uncontrollably, invade surrounding tissue, and spread through the blood or lymph channels to other parts of the body (e.g., liver, lungs, brain, bones), we call it breast cancer. This spread is also called metastatic cancer .

What are the symptoms of this disease? How can it be recognized early?

In most cases, there may be no symptoms in the early stages. However, if you are aware of your body, it is very important to be aware of these changes.

Having one or more of these symptoms doesn't necessarily mean it's cancer. But it's important to see a doctor and get checked out.

What are the risk factors for developing breast cancer?

"Why did this happen to me?" you may wonder. There is actually no single cause of breast cancer . It can be caused by a combination of factors. Let's break these down into two parts.

Risk factors we cannot control

• Age: Women over 50 are at higher risk.
• Family history: If your mother, sister, or daughter has had breast cancer, you are also at slightly higher risk.
• Genes: Some people have inherited genetic mutations (such as `BRCA1` and `BRCA2`) that increase their risk of cancer .
• Menstrual cycle: Starting menstruation before age 12 and stopping menstruation after age 55 slightly increase the risk.
• Previous radiation treatment: If you have received radiation treatment to the chest area for another disease.

Risk factors we can modify

• Body weight : Obesity is a risk factor, especially after menopause.
• Lack of exercise: Not having an active lifestyle.
• Alcohol use: Drinking alcohol daily increases the risk.
• Having children: Not having children or having your first child after age 30.
• Not breastfeeding: Not breastfeeding also slightly increases the risk.
• Some hormone treatments: Some hormone treatments for menopause can be taken for a long time. Talk to your doctor about this.

How exactly does the doctor find this?

When you see a doctor about a change in your breast, he or she will first examine you and ask about your family medical history. Then, if necessary, they may recommend some tests like these.

1. Imaging Tests:

• Mammogram: This is a specialized X-ray test of the breasts. It can detect lumps and other subtle changes.
• Ultrasound Scan: A test that uses sound waves to look inside the breast. This helps determine whether the lump is solid or fluid-filled.
• MRI Scan (Magnetic Resonance Imaging): In some special cases, this test is used to obtain a clearer picture.

2. Biopsy:

Simply put, this involves taking a very small piece of tissue (perhaps using a needle) from a suspicious tumor and examining it under a microscope. This test can provide a lot of information that is essential for planning treatment, such as whether cancer cells are present, what type they are, and how they behave (e.g., are they sensitive to hormones (`ER`, `PR` positive), or do they have too much of a protein called `HER2`).

What are the treatments?

If you are diagnosed with breast cancer, your medical team will develop a treatment plan that is best for you. It will depend on many things, such as the type and stage of your cancer, your age, and your overall health. There are several main treatment options.

1. Surgery

This is the main treatment method. There are two methods here.

• Lumpectomy: This involves removing the cancerous tumor and a small amount of healthy tissue around it, leaving the breast intact.
• Mastectomy: This is the surgical removal of the entire breast.

2. Radiation Therapy

After surgery, high-energy rays (like X-rays) are used to destroy any remaining cancer cells.

3. Drug treatment (Systemic Therapy)

Because these treatments affect the entire body, they are used to prevent the spread of cancer if it has spread.

• Chemotherapy: The use of powerful drugs to kill cancer cells. These are given as pills or through an injection into a vein.
• Hormone Therapy: If the cancer is hormone-dependent (ER/PR positive), drugs are given that block the action of those hormones.
• Targeted Therapy: These drugs target and attack a specific weakness in cancer cells (e.g., for `HER2` positive cancers).
• Immunotherapy: Giving drugs that help our body's own immune system recognize and fight cancer cells.
