Understanding Breast Cancer: Knowledge That Saves Lives

Important Disclaimer

This article provides general information about breast cancer for educational purposes only. It is not medical advice. It does not replace consultation with your healthcare team. Every patient is different. Every cancer is unique. Your doctors know your specific situation. They will recommend the best treatment plan for you. Always discuss your questions and concerns with your medical team. The final decisions about your care should be made together with your doctors.

Pink ribbons remind us of breast cancer. But symbols alone are not enough. We need real knowledge.

October is Breast Cancer Awareness Month. This is our time to learn, stay alert, and act. Breast cancer affects millions of women worldwide. It is one of the most common cancers women face.

Awareness campaigns have helped. More people know about breast cancer today. But confusion remains. Myths still spread. Many people don’t know the real causes. They miss early warning signs. They don’t understand treatment options.

This month, we change that. We replace fear with facts. We turn awareness into action.

This article is the first in a series about drug treatment for breast cancer. Drug therapy is one of the most important parts of breast cancer care. Yet many people do not fully understand it. My goal is to provide clear, accurate information. This knowledge will empower patients and families. It will help them make informed choices with confidence and hope.

Modern breast cancer care uses surgery, radiation, and medicines. All three are vital. This series will focus on drug therapy. To understand how these medicines work, we must first understand the disease. This article covers the basics: what breast cancer is, what causes it, how to recognize it, and how to reduce your risk.

Understanding Breast Cancer: The Essential Facts

Breast cancer starts when cells in the breast grow out of control. Normal cells grow and divide in an orderly way. Cancer cells do not follow these rules. They multiply rapidly. They form a mass called a tumor.

Not all tumors are cancer. Some tumors are benign. Benign tumors do not spread to other parts of the body. They are not life-threatening. Malignant tumors are cancer. These tumors can invade nearby tissues. They can spread through the blood or lymph system to other organs. This spreading is called metastasis.

Breast cancer can start in different parts of the breast. Most begin in the ducts that carry milk. Some start in the glands that make milk. A few start in other breast tissues.

What Causes Breast Cancer?

Doctors do not know the exact cause of every breast cancer. We cannot point to one single reason. However, research shows that certain risk factors increase a person’s chance of getting the disease.

Uncontrollable Risk Factors

These are risks you cannot change.

• Being a woman: Breast cancer is much more common in women than in men.
• Getting older: Risk increases significantly with age. Most breast cancers occur after age 50.
• Genetics: Inherited gene mutations, like BRCA1 and BRCA2, raise the risk substantially. These mutations run in families.
• Family history: Having a close relative with breast cancer increases your risk. The risk is higher if the relative was diagnosed at a young age.
• Dense breast tissue: Some women have more dense tissue in their breasts. This increases risk. It also makes mammograms harder to read.
• Early periods or late menopause: Starting periods before age 12 or entering menopause after age 55 increases exposure to hormones. This raises risk slightly.

Lifestyle Risk Factors

These are risks you can influence through your choices.

• Alcohol: Drinking alcohol increases the risk of breast cancer. Even small amounts add to risk.
• Weight: Being overweight or obese after menopause raises the risk. Fat tissue produces estrogen. More estrogen can fuel breast cancer growth.
• Physical activity: Being inactive increases your risk. Regular exercise helps protect against breast cancer.
• Hormone therapy: Taking combined hormone replacement therapy after menopause for several years increases risk.

Here is an important truth: Many people with breast cancer have no known risk factors except being a woman and growing older. You can do everything right and still develop breast cancer. This is why screening is so important.

Recognizing the Symptoms

You know your body best. Pay attention to changes. See a doctor if you notice any of these signs:

• A new lump in the breast or underarm
• Thickening or swelling of part of the breast
• Irritation or dimpling of breast skin
• Redness or flaky skin on the nipple or breast
• A nipple that pulls inward
• Nipple discharge other than breast milk, especially if bloody
• Any change in the size or shape of the breast
• Pain in any area of the breast that does not go away

Many of these symptoms can be caused by other health issues. Most breast lumps are not cancer. However, a doctor must check any changes to be sure. Early detection saves lives. Do not wait. Do not hope symptoms will go away.

How Doctors Diagnose Breast Cancer

If you have symptoms or an abnormal screening test, your doctor will do more tests. A diagnosis involves several steps.

Clinical Exam: A doctor or nurse carefully examines your breasts and underarms. They feel for lumps or other changes.

Imaging Tests: These tests create pictures of the inside of the breast.

• A mammogram is an X-ray of the breast. It is the most common screening tool. It can find tumors too small to feel.
• An ultrasound uses sound waves to create images. It helps doctors see if a lump is solid or filled with fluid.
• An MRI uses magnets and radio waves. It provides very detailed images. Doctors use it in certain situations.

Biopsy: This is the only way to confirm cancer. A doctor removes a small sample of tissue from the suspicious area. A specialist called a pathologist examines the cells under a microscope. The pathologist determines if cancer is present. The biopsy also provides information about the type of cancer. This information guides treatment decisions.

How to Reduce Your Risk

You cannot prevent breast cancer completely. But you can take steps to lower your risk.

Make Healthy Lifestyle Choices

• Maintain a healthy weight: This is especially important after menopause.
• Be physically active: Aim for at least 150 minutes of moderate exercise each week. This is about 30 minutes on most days. Walking, swimming, dancing—choose activities you enjoy.
• Limit alcohol: If you drink, limit yourself to no more than one drink per day. Less is better.
• Breastfeed if you can: Breastfeeding for several months may reduce risk.
• Avoid hormone therapy when possible: If you need hormone therapy for menopause symptoms, use the lowest dose for the shortest time.

Get Regular Screenings

Screening finds breast cancer early, when it is most treatable. Talk to your doctor about when to start screening. Guidelines vary based on age and risk factors.

• Average risk women: Most should start annual mammograms at age 40 to 50. Continue as long as you are in good health.
• High risk women: You may need to start screening earlier. You may need additional tests like MRI. Discuss your risk with your doctor.

Know Your Family History

Talk to your relatives about cancer in your family. Tell your doctor if you have close relatives with breast, ovarian, or other cancers. You may benefit from genetic counseling. Some high-risk women choose genetic testing. If you carry a high-risk gene mutation, your doctor can discuss additional prevention options.

Looking Ahead

Understanding these fundamentals is your first step toward empowerment. You now know what breast cancer is. You know the risk factors. You can recognize warning signs. You understand how doctors find and diagnose the disease. You know how to reduce your risk.

In our next article, we begin our journey into drug therapy. We will explore how medicines have transformed breast cancer treatment. We will learn why drug therapy has become essential, even for cancers that seem completely removed by surgery. You will understand the goals of treatment and where we stand today.

Knowledge removes fear. Understanding brings strength. Together, we will navigate this path with clarity and hope.
