Breast Cancer and Pink October: Your Guide to Awareness and Early Detection

Every October, the world observes Breast Cancer Awareness Month, also known as “Pink October.” It is an important opportunity to remind every woman of the importance of taking care of her breast health, understanding breast cancer risk factors, recognizing warning signs, and learning about the appropriate screening options.

Breast cancer is one of the most common types of cancer among women worldwide. According to the World Health Organization (WHO), approximately 2.4 million women were diagnosed with breast cancer in 2024, with around 670,000 deaths reported globally. At the same time, early detection, timely diagnosis, and appropriate treatment can help improve outcomes and reduce breast cancer mortality.

For this reason, the goal of Pink October goes beyond wearing pink or sharing awareness messages. It encourages women to become more familiar with their bodies, pay attention to unusual breast changes, and understand when they should consult a doctor or undergo appropriate breast examinations.

What Is Breast Cancer?

Breast cancer is a disease that occurs when some cells in the breast begin to grow and divide abnormally and uncontrollably. These cells may form a tumor and, in some cases, cancer cells can spread to surrounding tissues or other parts of the body.

There is more than one type of breast cancer, and different types can vary in their characteristics, growth patterns, and response to treatment. Therefore, treatment decisions depend on the type and stage of the tumor, as well as the individual medical characteristics of each case.

It is also important to understand that finding a lump in the breast does not necessarily mean that it is cancer. Many breast lumps are benign. However, any new or unusual lump or breast change should be medically evaluated to determine its cause.

Why Is October Breast Cancer Awareness Month?

October is recognized worldwide as Breast Cancer Awareness Month. During this month, healthcare organizations and professionals work to increase awareness of breast cancer, encourage women to understand risk factors and warning signs, and emphasize the importance of early diagnosis and access to appropriate medical care.

The 2026 Breast Cancer Awareness Month campaign carries the message “Every story is unique, every journey matters,” highlighting that every woman’s experience with breast cancer is different and that each patient deserves care and support tailored to her individual needs.

The importance of Breast Cancer Awareness Month lies in turning awareness into practical action. Recognizing potential breast cancer signs and seeking medical evaluation when needed can help identify the disease earlier and ensure timely access to appropriate care.

What Are the Symptoms of Breast Cancer?

Breast cancer may not cause noticeable symptoms in its early stages. This is why appropriate screening and medical follow-up remain important, even when there are no obvious symptoms.

Some changes that should receive medical attention include:

1. A New Lump in the Breast

A lump, area of thickening, or firm area may develop in the breast. A lump may also appear in the armpit.

Having a lump does not automatically mean that it is cancer. However, any new or unusual lump should be evaluated by a healthcare professional, even if it is not painful.

2. Changes in the Size or Shape of the Breast

A new and noticeable change in the size or shape of one breast should be taken seriously, especially when there is no obvious explanation for the change.

3. Changes in the Skin of the Breast

Changes may include dimpling, puckering, redness, swelling, or other noticeable changes in the appearance of the breast skin.

4. Changes in the Nipple

A new change in the appearance or position of the nipple, or changes in the skin around the nipple, should be evaluated, particularly if the change is different from what is normal for you.

5. Unusual Nipple Discharge

Unusual discharge from the nipple, particularly bloody discharge, should be medically evaluated.

6. Changes in the Armpit

A lump or swelling may appear in the armpit due to changes involving the lymph nodes. Any persistent or unusual swelling should be assessed by a healthcare professional.

It is important to remember that having one of these symptoms does not necessarily mean that you have breast cancer. However, new or persistent breast changes should not be ignored.

Does Breast Cancer Cause Pain?

Not necessarily.

Breast cancer can sometimes be associated with pain or other changes, but the presence or absence of pain alone cannot determine the nature of a breast change.

Breast cancer, particularly in its early stages, may not cause noticeable symptoms. Therefore, women should not wait for pain or another specific symptom before seeking appropriate medical evaluation.

What Are the Risk Factors for Breast Cancer?

Several factors can affect a woman’s risk of developing breast cancer. Some of these factors cannot be changed, such as age, family history, and certain genetic factors.

Known breast cancer risk factors include:

• Increasing age.
• A family history of breast cancer, particularly among close relatives.
• Certain inherited genetic mutations, including BRCA1, BRCA2, and PALB2.
• A previous diagnosis of breast cancer.
• Certain previous breast conditions or changes in breast tissue.
• Previous radiation exposure to the chest, particularly at a young age.
• Being overweight or obese, particularly after menopause.
• Certain lifestyle-related factors.

Having one or more risk factors does not mean that a woman will definitely develop breast cancer. Likewise, not having known risk factors does not mean that there is no possibility of developing the disease.

According to the World Health Organization, around 80% of breast cancer cases occur in women who have no specific risk factors other than sex and age.

How Can You Reduce the Risk of Breast Cancer?

There is no guaranteed way to prevent breast cancer completely. However, certain healthy lifestyle habits may help reduce some risk factors.

Helpful steps may include:

• Maintaining a healthy weight.
• Engaging in regular physical activity.
• Avoiding or limiting alcohol consumption.
• Taking care of your overall health and maintaining appropriate medical follow-up.
• Knowing your family history and discussing your individual risk with your doctor if there is a history of breast cancer in your family.

Research indicates that maintaining a healthy weight, being physically active, and limiting alcohol consumption may help reduce the risk of breast cancer.

Why Is Early Detection of Breast Cancer Important?

Early detection is one of the most important messages highlighted during Breast Cancer Awareness Month.

The goal of early detection is to identify breast cancer or suspicious changes at an earlier stage, before the disease progresses or symptoms become more noticeable in some cases. The World Health Organization emphasizes that early diagnosis and timely treatment can improve outcomes and help reduce breast cancer mortality.

It is important to distinguish between three different aspects of breast health:

Breast Awareness

Breast awareness means becoming familiar with how your breasts normally look and feel and paying attention to any new or unusual changes.

Clinical Breast Examination

A clinical examination is performed by a doctor or healthcare professional to assess breast symptoms or changes.

Breast Cancer Screening

Breast cancer screening refers to examinations performed to detect breast cancer before symptoms appear in certain groups of women. The appropriate screening method and timing depend on factors such as age, risk level, and medical and family history.

What Is a Breast Ultrasound?

A breast ultrasound, also known as Breast Ultrasound, is an imaging test that uses sound waves to create images of the tissues inside the breast.

A breast ultrasound may be used to evaluate a specific area, lump, or breast change identified during an examination. It may also be used alongside other breast imaging tests depending on the individual case.

It is important to understand that breast ultrasound and mammography are not necessarily alternatives to each other. The appropriate imaging test depends on factors such as age, symptoms, risk level, clinical examination findings, and the doctor’s assessment.

What Is a Mammogram?

A mammogram, or mammography, is an X-ray examination of the breasts. It is one of the main screening tools used for the early detection of breast cancer in women who are eligible for screening.

Mammography can detect certain breast changes associated with cancer before they become large enough to be felt or before noticeable symptoms appear.

However, the appropriate age to start screening and how often it should be performed can vary depending on age, individual risk factors, and current medical recommendations. Therefore, it is best to discuss your personal breast cancer screening plan with your doctor rather than following one schedule that applies to every woman.

Is Breast Self-Examination Enough to Detect Breast Cancer?

No.

Being familiar with the normal appearance and feel of your breasts and noticing new changes can help you pay attention to your breast health. However, breast awareness does not replace clinical evaluation or recommended breast cancer screening.

Early breast cancer may not cause noticeable symptoms, and some changes cannot be detected through touch alone. The appropriate screening approach depends on factors such as age, risk factors, medical history, and professional medical assessment.

When Should You See a Doctor?

You should consider consulting a doctor if you notice any new or persistent change in your breast, particularly if you experience:

• A new lump in the breast.
• Thickening or a firm area in the breast.
• A noticeable change in the size or shape of the breast.
• Changes in the breast skin.
• A new change in the nipple.
• Unusual or bloody nipple discharge.
• A lump or swelling in the armpit.

You should not wait until a breast change becomes painful before seeking medical advice. Some breast cancers may not cause pain, particularly in the early stages.

Breast Cancer Is Not Limited to a Specific Age

Although the risk of breast cancer generally increases with age, breast cancer can occur at different ages.

Having a family history of breast cancer or certain inherited genetic factors may increase a woman’s risk. As a result, breast cancer screening and follow-up needs can vary from one woman to another.

Therefore, the important question is not only, “When should I start breast cancer screening?” but also, “Which breast screening test is right for me, and when should I have it?”

The answer depends on several factors, including age, personal and family medical history, current symptoms, and individual risk factors.

Pink October: An Opportunity to Care for Your Health All Year Long

October is Breast Cancer Awareness Month, but breast health should not be a once-a-year concern.

True awareness starts with knowing your body, paying attention to new or unusual changes, understanding your personal risk factors, and following the breast screening recommendations that are appropriate for you.

If you notice an unusual breast change, do not simply wait for it to disappear. Consult a doctor or healthcare professional to determine the appropriate next step.

Early detection does not mean expecting to develop breast cancer. It means giving your health the attention and care it deserves.
