preventing breast

Overview

Breast cancer is a disease in which cells in the breast grow out of control. 'Preventing breast cancer' means taking steps to lower your chances of getting it. While you cannot control some risks like age and genes, many lifestyle choices can help.

Yes. Breast cancer is the most common cancer in women worldwide. About 1 in 8 women will be diagnosed in their lifetime. But many people survive it, especially when it is found early.

Breast cancer mostly affects women over the age of 50. Men can also develop it, but it is much rarer. You can get breast cancer even if no one in your family has had it.

Symptoms

Common symptoms

• A new lump or thickening in the breast or armpit
• A change in breast size or shape
• Dimpling or puckering of the breast skin (like an orange peel)
• A nipple that turns inward
• Nipple discharge, especially if it happens without squeezing
• Redness, scaling, or a rash on the breast or nipple

Symptoms in children

• Breast cancer is extremely rare in children. Lumps in a child's breast are almost always harmless, but a doctor should check any new lump to be sure.

Symptoms in older adults

• As people get older, breast cancer becomes more common. Older adults may notice the same symptoms as younger people. Even after menopause, any new breast change should be checked by a doctor.

Causes

Main causes

• Breast cancer starts when cells in the breast get changes in their DNA that make them grow out of control. The exact reason for these changes is not fully understood.
• Hormones, especially estrogen, can help some breast cancers grow.
• Some people inherit gene changes (like BRCA1 or BRCA2) from their parents, which raises risk, but these cause only a small number of breast cancers.

Risk factors

• Being female
• Getting older
• Having a close family member with breast or ovarian cancer
• Carrying a BRCA1 or BRCA2 gene change (learned from genetic testing)
• Starting your period before age 12 or menopause after age 55
• Having no children or having your first child after age 30
• Taking combined hormone replacement therapy for many years
• Drinking alcohol
• Smoking or secondhand smoke
• Being overweight after menopause

When to see a doctor

See a doctor urgently if:

• Any new lump or thickening in your breast or armpit
• Nipple discharge that is spontaneous and not milk
• Skin changes on the breast such as dimpling, redness, or a persistent rash
• One breast that is swollen or looks different from the other for no clear reason

Book a routine appointment if:

• If you are due for a screening mammogram, schedule it
• If you have a strong family history of breast or ovarian cancer, ask your doctor about risk assessment
• If you have breast pain that worries you, bring it up at your next appointment

Diagnosis

To diagnose breast cancer, your doctor will start with a conversation about your symptoms, health history, and a clinical breast exam. If needed, they will order imaging tests and, sometimes, a biopsy to confirm whether cancer is present.

Tests that may be done

• Clinical breast exam (a doctor feels the breast and armpit)
• Mammogram (a low-dose X-ray of the breast)
• Ultrasound (uses sound waves to create pictures of breast tissue)
• MRI (magnetic resonance imaging) in some cases
• Biopsy (removing a tiny piece of tissue to look at under a microscope)

What to expect at your appointment

Tests may feel awkward or uncomfortable, but they are usually quick. A mammogram squeezes the breast for a few seconds to get a clear image. A biopsy uses numbing medicine, so you should not feel sharp pain. Results can take a few days to a week. Your doctor will explain the results and, if cancer is found, talk about what happens next.

Treatment

If you are diagnosed with breast cancer, you will have a care team that creates a personal plan. Treatment depends on the type, size, and stage of the cancer, as well as your overall health. You will be guided through every step with clear explanations.

Self-care at home

• Attend all appointments and follow the plan your team suggests
• Ask for help with household tasks when you are tired
• Keep a diary of side effects and share it with your care team
• Do light activities like short walks if you feel up to it

Medical treatments

Treatments may include surgery to remove the cancer, radiation therapy that uses high-energy rays to destroy cancer cells, chemotherapy that uses medicines to kill fast-growing cells, hormone therapy that blocks hormones like estrogen from fueling the cancer, and targeted therapy that attacks certain parts of cancer cells. You may receive one or a combination of these. Your doctor will discuss pros and cons and what to expect. No specific medication names are needed here; your medical team will recommend the right options for you.

When is surgery considered?

Surgery is often part of breast cancer treatment. A lumpectomy removes only the tumor and a small rim of healthy tissue. A mastectomy removes the entire breast. Your doctor may also remove some underarm lymph nodes to see if the cancer has spread. Your surgical team will explain the options, expected recovery, and any breast reconstruction choices.

Living with this condition

Life after a breast cancer diagnosis takes time to adjust. Try to keep a simple, gentle routine. Let others help you. Stay in touch with your care team for any concerns. Many people find a 'new normal' and live full, meaningful lives.

Lifestyle tips

• Join a cancer support group — in person or online
• Ask your care team about exercise programs for cancer survivors
• Try relaxation techniques like deep breathing or meditation
• Set small, realistic goals to celebrate each day

Diet and exercise

Eat a balanced diet with lots of vegetables, fruits, whole grains, and lean protein. Limit alcohol and highly processed foods. Regular exercise like walking, swimming, or yoga can help you feel stronger and more hopeful. Always check with your doctor before starting something new.

Mental health and emotional wellbeing

A breast cancer diagnosis can bring fear, sadness, anger, and worry. These feelings are common and normal. Talking to a counsellor or psychologist can make a big difference. If you ever feel overwhelmed or have thoughts of harming yourself, please reach out to a crisis line or local emergency service right away. You are not alone.

Prevention

There is no guaranteed way to prevent breast cancer, but you can lower your risk. Staying physically active, keeping a healthy weight, limiting alcohol, and avoiding smoking all help. If you are at very high risk because of your genes or family history, your doctor may suggest extra screening or preventive options. Talk to your healthcare provider about your personal risk.

Screening programmes

Screening checks for breast cancer before you have symptoms. Mammograms are the main test used. According to many health guidelines, women aged 50 to 70 are often offered a mammogram every three years. Women with higher risk may be offered earlier or more frequent screening. Ask your doctor which schedule is right for you.

Complications

If left untreated

• Without treatment, breast cancer may grow into nearby breast tissue and spread to lymph nodes under the arm.
• Cancer may spread to distant organs like bones, liver, or lungs, which makes treatment much more difficult.
• In advanced stages, the disease can lead to serious symptoms and become life-threatening.

Long-term outlook

The outlook for breast cancer has improved dramatically over the last few decades. Most women treated early are cured or live with the disease for many years. Today's treatments are more personalized and effective. Even if your cancer is advanced, there are many ways to control it and maintain a good quality of life. You will be supported every step of the way.
