Xổ số miền bắc thứ 4 hàng tuầnBreast cancer symptoms vary from person to person and there is no exact definition of what a lump or mass feels like. The best thing to do is to be familiar with your breasts so you know how “normal” feels and looks. If you notice any changes, tell your doctor. However, many breast cancers are found by mammograms before any symptoms appear.
Breast cancer symptoms may include:
- Lump or mass in the breast
- Lump or mass in the armpit
- Skin redness
- Dimpling or puckering on the breast
- Scaliness on nipple (sometimes extending to the areola)
- Discharge from the nipple
- Nipple changes, including the nipple turning inward, pulling to one side or changing direction
- Ulcer on the breast or nipple (sometimes extending to the areola)
- Thickening of the skin, resulting in an orange-peel texture
These symptoms do not always mean you have breast cancer. However, it is important to discuss any symptoms with your doctor, since they may also signal other health problems.
Types of breast cancer
Most types of breast cancer can be classified as either ductal carcinomas or lobular carcinomas. Lobular carcinomas start in the breasts’ milk-producing glands, called the lobules. Ductal carcinomas start in the cells of the milk ducts, which carry milk from the lobules to the nipples.
Both can be non-invasive, meaning the diseased cells have not spread into surrounding normal tissue. Non-invasive diseases are by definition early in the cancer development process. In fact, non-invasive lobular carcinoma is so early that it’s not even classified as cancer. Instead, it is considered a cancer risk factor and may not even require surgery.
Both ductal and lobular carcinomas can also be invasive, meaning cancer has spread beyond the lobule or duct where it first started into nearby tissue.
Breast cancer treatments are designed around several factors, including whether the cancer is ductal or lobular and invasive or non-invasive.
For invasive breast cancers, another key factor is the molecular receptor status of the cancer cells.
Receptors are molecules that cancer cells produce on their surface. These receptors can interact or bind with specific proteins and hormones in the patient’s body. This interaction is known as recognition.
Xổ số miền bắc thứ 4 hàng tuầnResearchers have identified certain receptors that fuel the growth and spread of breast cancer when they recognize, or bind, with a specific molecule. By interrupting this recognition with new cancer drugs, the disease’s growth can be slowed or stopped.
Currently, there are three major receptor subtypes that play important roles in the patient’s prognosis and treatment. As research into breast cancer continues, more subtypes with different treatments are likely to emerge. The three main subtypes are listed below.

Molecular receptor subtypes
HER2 is a protein that promotes cell growth and multiplication. It is found on the surface of all breast cells. A breast cancer is HER2-positive when it has much higher levels of the protein than normal.
About half of HER2-positive cancers are also hormone receptor-positive/ER positive. These patients receive treatments that target both molecular receptors. They are classified as HER2-positive since doctors believe HER2 is the primary driver of the disease.
A HER2-positive diagnosis was at one time associated with a higher risk of recurrence. Recent treatment advances, particularly with targeted therapiesXổ số miền bắc thứ 4 hàng tuần, have made the disease more curable in its early stages. They have also extended the survival period for patients whose cancer has spread beyond the breast and nearby lymph nodes.
Hormone receptor-positive breast cancer (sometimes called Luminal A) has receptors that bind with one of two naturally occurring hormones, estrogen and progesterone. These hormones fuel the growth of the cancer by binding to these receptors.
Xổ số miền bắc thứ 4 hàng tuầnEndocrine therapies target this receptor/hormone recognition. These therapies can limit the body’s production of estrogen and progesterone or stop the receptors from recognizing the hormones.
Thanks to this therapy and the cancer’s tendency to spread relatively slowly, hormone receptor-positive breast cancer is considered the most treatable form of the three main subtypes.
Xổ số miền bắc thứ 4 hàng tuầnTriple-negative breast cancer (sometimes called basal breast cancer) covers most breast cancers that don’t have one of the other three receptors. Besides this, triple-negative breast cancers can have very little in common.
Since there isn’t an established receptor to target in triple-negative breast cancer, this is the most difficult of the three receptor subtypes to treat. Triple-negative breast cancer also tends to be more aggressive, so the prognosis for this subtype is often worse than others. Some triple-negative breast cancers, however, do respond well to chemotherapy. In some cases, chemotherapy works so well that no cancer is found during surgery. This is called a pathological complete response.
Other types of breast cancer
Xổ số miền bắc thứ 4 hàng tuầnInflammatory breast cancer accounts for 2%-4% of all breast cancer diagnoses in the United States. The disease is aggressive and makes up about 10% of all breast cancer deaths in the U.S. In this disease, cancer cells block lymph vessels in the skin and soft tissue. Inflammatory breast cancer is also classified by its receptor status and is more often triple-negative or HER2-positive than non-inflammatory breast cancer.
Xổ số miền bắc thứ 4 hàng tuầnMetaplastic breast cancer is rare, making up less than 1% of all breast cancers. Most patients have a distinct lump that grows quickly. The disease is aggressive and usually has a triple-negative receptor type. It is difficult to treat successfully.
Xổ số miền bắc thứ 4 hàng tuầnWhile breast cancer is thought of as a disease impacting women, each year about 2,500 men in the United States are diagnosed with the disease. Like female breast cancer, most cases fall into the three receptor subtype groups (HER2-positive, hormone receptor-positive and triple-negative).
Xổ số miền bắc thứ 4 hàng tuầnPaget disease is a rare form of breast cancer, making up 1-4% of all breast cancer cases, according to the National Cancer Institute. The disease first appears on the nipple and often extends to the areola.
Xổ số miền bắc thứ 4 hàng tuầnAdvanced breast cancer (also called metastatic breast cancer and stage IV breast cancer) is not a distinct type of cancer. Instead, it is any breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body, such as the bones, brain, liver or lungs. Even though the disease may be found in other organs, it is still considered and treated like breast cancer.
Most cases of advanced breast cancer are not considered curable. Instead, they are treated like a chronic illness. The goal of care is to prolong life and maintain the patient’s quality of life. With emerging therapies and treatments, many metastatic breast cancer patients can live well for years. MD Anderson has an Advanced Breast Cancer ClinicXổ số miền bắc thứ 4 hàng tuần dedicated to caring for these patients.
Breast cancer risk factors
A risk factor is anything that increases the chances of developing a specific disease. Key risk factors and causes include:
- Age: As women age, their breast cancer risk increases. Most breast cancers are diagnosed after age 50. If you believe you may be more likely to develop cancer because of your personal or family medical history, please review our screening exams by age.
- Inherited genetic mutations: Specific gene mutations increase the risk of developing cancer. These include the BRCA1 and BRCA2 mutations. Normal BRCA1 and BRCA2 genes repair damaged DNA. When these genes are mutated in certain ways, they fail at DNA repair, which could lead to breast and/or ovarian cancer. Other genes mutations associated with a higher risk of cancer include PALB2, another DNA repair gene; CHEK2, a tumor suppressor; and PTEN, which controls how quickly cells multiply. Learn more about hereditary cancer syndromes.
- Family history: A woman’s odds of developing breast cancer increase if a parent, sibling or child has had the disease.
- Early menstruation: Women who began menstruating before age 12 have a higher risk of developing breast cancer.
- Women who have no full-term pregnancies or their first pregnancy after age 30 are at a higher risk of breast cancer.
- Previous breast cancer diagnosis: A woman who has had breast cancer once has a higher risk of developing a second cancer.
- Previous radiation therapy to the chest in childhood or early adulthood increases the risk of developing breast cancer.
- Obesity, particularly after menopause, increases a woman’s breast cancer risk.
- Dense breast tissue based on its appearance in a mammogram is a known risk factor for breast cancer.
