Types of Breast Cancer
There are several types. Each type behaves differently and may need different treatments. Let’s look at the main types.
Types of Noninvasive Breast Cancer
Noninvasive breast cancers stay in one place. They don’t spread to other parts of the body. The two main types are:
- Ductal Carcinoma In Situ (DCIS): This cancer starts in the milk ducts. It hasn’t spread beyond the ducts.
- Lobular Carcinoma In Situ (LCIS): This type starts in the milk-producing glands. It’s often considered a risk factor for future breast cancer rather than itself.
Types of Invasive Breast Cancer
Invasive breast cancers can spread to other parts of the body. The main types are:
- Invasive Ductal Carcinoma (IDC): This is the most common type. It starts in the milk ducts and spreads to nearby tissue.
- Invasive Lobular Carcinoma (ILC): This type starts in the milk glands and can spread.
- Inflammatory: This rare type makes the breast look red and swollen.
- Triple-Negative: This type doesn’t have the most common receptors found in breast cancer. It can be harder to treat.
How Common is Breast Cancer?
Breast cancer is very common. In the USA, about 1 in 8 women will get breast cancer in their lifetime. For men, the risk is much lower, about 1 in 833. Each year, over 250,000 new cases are diagnosed in women in the USA.
Risk Factors
Many things can increase your risk of breast cancer. Some you can’t change, like your age or genes. Others you can control, like your lifestyle. Here are some key risk factors:
- Being a woman
- Getting older
- Having a family history of breast cancer
- Carrying certain gene mutations, like BRCA1 or BRCA2
- Starting periods early or menopause late
- Not having children or having your first child after age 30
- Being overweight or obese
- Drinking alcohol regularly
- Not getting enough exercise
Remember, having risk factors doesn’t mean you’ll get breast cancer. And some people with no risk factors still get the disease. Regular check-ups and a healthy lifestyle are your best defense.
Diagnosis of Breast Cancer
Finding breast cancer early is crucial. There are several ways doctors can check for breast cancer. Let’s look at the main methods.
Imaging Tests
Mammogram screening is the most common test. It’s an X-ray of the breast that can show tumors before you can feel them. Women over 40 should get mammograms regularly. How often depends on your risk factors.
Other imaging tests include:
- Ultrasound: This uses sound waves to create images of the breast.
- MRI: This uses magnets and radio waves to make detailed pictures of the breast.
These tests can help doctors see if a lump might be cancer.
Breast Biopsy
If imaging tests show something suspicious, you might need a breast biopsy. This means taking a small sample of breast tissue to check for cancer cells. There are different types of biopsies:
- Fine-needle aspiration: Uses a thin needle to remove fluid or cells from a lump.
- Core needle biopsy: Uses a larger needle to remove a small cylinder of tissue.
- Surgical biopsy: Removes part or all of a lump through surgery.
A pathologist looks at the tissue under a microscope to check for cancer cells. This test can confirm if you have breast cancer and what type it is.
Stages
If you’re diagnosed with breast cancer, the doctor will determine its stage. The stage tells how far the cancer has spread. It helps guide treatment decisions. There are five main stages of breast cancer.
Stage 0
This is the earliest stage. It’s also called carcinoma in situ. The cancer cells are only in the layer where they started. They haven’t spread to other tissues. Stage 0 cancers are highly treatable.
Stage 1
In Stage 1, the tumor is small and hasn’t spread beyond the breast. There are two sub-stages:
- Stage 1A: The tumor is 2 cm or smaller and hasn’t spread outside the breast.
- Stage 1B: Small clusters of cancer cells (0.2mm to 2mm) are found in the lymph nodes.
Stage 2
Stage 2 breast cancer is still considered early-stage breast cancer. The cancer has grown but is still contained in the breast or nearby lymph nodes. There are two sub-stages:
- Stage 2A: The tumor is larger than Stage 1 but not larger than 5 cm.
- Stage 2B: The tumor is larger than 5 cm but hasn’t spread to lymph nodes.
Stage 3
In Stage 3, the cancer has spread beyond the nearby lymph nodes or muscles. It hasn’t spread to distant parts of the body. There are three sub-stages (3A, 3B, 3C) based on tumor size and how many lymph nodes are involved.
Stage 4 (Metastatic Breast Cancer)
This is the most advanced stage. The cancer has spread to other parts of the body, like the bones, lungs, liver, or brain. It’s also called metastatic breast cancer. While it’s the most serious stage, many people live for years with stage 4.
Breast Cancer Treatment
Treatment for breast cancer depends on many factors. These include the type of breast cancer, its stage, and your overall health. Most people have more than one type of treatment. Let’s look at the main options.
Surgery
Surgery is often the first treatment. There are two main types:
- Lumpectomy: Removes the tumor and some surrounding tissue, but leaves most of the breast intact.
- Mastectomy: Removes the entire breast.
The type of surgery depends on the size and location of the tumor, and your personal preferences. After mastectomy, some women choose breast reconstruction surgery.
Radiation Therapy
Radiation therapy uses high-energy rays to kill cancer cells. It’s often used after surgery to kill any remaining cancer cells. There are two main types:
- External beam radiation: Radiation comes from a machine outside the body.
- Internal radiation (brachytherapy): Radioactive seeds are placed inside the cancer.
Radiation can cause side effects like skin changes and fatigue. These usually go away after treatment ends.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells throughout the body. It’s often used before or after surgery. Chemo can also be used for advanced breast cancer to slow its growth.
Chemo drugs are usually given through a vein (IV) or as pills. They travel through the bloodstream to reach cancer cells anywhere in the body. Side effects can include hair loss, nausea, and fatigue.

Hormone Therapy
Some breast cancers need hormones to grow. Hormone therapy for these cancers can slow or stop their growth. It’s often used after surgery to help prevent the cancer from coming back.
There are several types of hormone therapy:
- Tamoxifen: Blocks estrogen from attaching to cancer cells.
- Aromatase inhibitors: Lower the amount of estrogen in the body.
- Ovarian suppression: Stops the ovaries from making estrogen.
Side effects can include hot flashes, night sweats, and bone thinning.
Breast Cancer Prevention
While you can’t prevent all breast cancers, there are ways to lower your risk. Here are some key strategies for breast cancer prevention.
Lifestyle Factors
Your daily habits can affect your breast cancer risk. Here are some tips:
- Maintain a healthy weight
- Exercise regularly
- Limit alcohol intake
- Eat a healthy diet rich in fruits and vegetables
- Don’t smoke
- Breastfeed if possible
These habits are good for your overall health too.
Breast Cancer Screening
Regular screening can help find breast cancer early when it’s most treatable. The main screening test is the mammogram. Here are the current guidelines:
- Women 40-44: Can start yearly mammograms if they wish
- Women 45-54: Should get mammograms every year
- Women 55 and older: Can switch to mammograms every 2 years, or continue yearly screening
Talk to your doctor about what’s right for you. Some women at high risk may need to start screening earlier or have additional tests.
Preventive Treatment
For women at very high risk, there are medical options to lower risk:
- Risk-reducing medications: Drugs like tamoxifen can lower breast cancer risk in some women.
- Preventive surgery: Some women with very high risk due to gene mutations choose to have their breasts removed before cancer develops.
These are big decisions. Talk to your doctor about your personal risk and options.
Self-Exams
Knowing how your breasts normally look and feel can help you notice changes. Many doctors no longer recommend formal self-exams. But being familiar with your breasts is still a good idea. If you notice any changes, see your doctor.
Breast Exam by Your Doctor
Your doctor may do a breast exam during your regular check-up. They’ll check for any lumps or changes in your breasts. This is a good time to discuss any concerns you have about your breast health.
Breast Cancer Survival Rate
The survival rate has improved a lot over the years. Today, the overall 5-year survival rate for USA is about 90%. This means 90 out of 100 women with cancer are still alive 5 years after diagnosis.
Survival rates vary based on the stage of cancer:
- Stage 0 & 1: Nearly 100% 5-year survival rate
- Stage 2: About 93% 5-year survival rate
- Stage 3: About 72% 5-year survival rate
- Stage 4: About 22% 5-year survival rate
Remember, these are averages. Many factors affect an individual’s outlook, including age, overall health, and how well the cancer responds to treatment.
