Breast cancer is cancer that is found inside the cells of the breasts.

After pores and skin cancer, breast cancer  is the most common cancers identified in women in America. Breast most cancers can arise in both ladies and men, however it's far common in ladies.
Massive assistance for breast cancers recognition and research investment has helped created advances in the prognosis and treatment of most breast cancers.  survival rates have increased, and the variety of deaths related to this disorder is gradually declining, largely because of factors such as  advance detection, a new personalised method to remedy and a better knowledge of the disorder.

 Symptoms of breast cancer
Symptoms of breast cancer

Symptoms of breast tumors range from person to person. 
A few not unusual, early warning symptoms of breast most cancers include:
  • Pores and skin changes, which include swelling, redness, or  differences seen  in a single or both breasts.
  • Change in length or form of the breast(s).
  • Changes in the appearance of 1 or both nipples
  • Nipple discharge aside from breast milk.
  • Popular pain in/on any a part of the breast
  • Lumps or nodes felt on  the breast
Symptoms of invasive breast  cancers are:
  • Angry or itchy breasts
  • Change in breast colour
  • Increase in breast length or shape (over a brief time frame)
  • Modifications in contact (can also sense hard, gentle or warm)
  • Peeling or flaking of the nipple pores and skin
  • A breast lump or thickening
  • Redness or pitting of the breast skin (like the skin of an orange) 
It's crucial to understand that different, benign conditions may additionally have triggered these changes. For instance, adjustments to the pores and skin texture at the breast can be because of a skin situation like eczema, and swollen lymph nodes may be caused by an contamination inside the breast or any other, unrelated contamination. Seeing a doctor for an assessment will assist you decide whether something you note is cause for concern.

Types of breast Cancer
Types of breast Cancer

Types of breast cancer include ductal carcinoma in situ, invasive ductal carcinoma, inflammatory breast cancer, and metastatic breast cancer.
In situ vs. invasive breast cancers
The type of breast cancer can also refer to whether the cancer has spread or not. In situ breast cancer (ductal carcinoma in situ or DCIS) is a cancer that starts in a milk duct and has not grown into the rest of the breast tissue. The term invasive (or infiltrating) breast cancer is used to describe any type of breast cancer that has spread (invaded) into the surrounding breast tissue.
Ductal carcinoma in situ
Ductal carcinoma in situ (DCIS; also known as intraductal carcinoma) is a non-invasive or pre-invasive breast cancer. 
Invasive breast cancer (ILC or IDC)
Invasive (or infiltrating) breast cancer has spread into surrounding breast tissue. The most common types are  invasive ductal carcinoma and invasive lobular carcinoma. Invasive ductal carcinoma makes up about 70-80% of all breast cancers. 
Special types of invasive breast cancers
Some invasive breast cancers have special features or develop in different ways that affect their treatment and outlook. These cancers are less common but can be more serious than other types of breast cancer.
Triple-negative breast cancer
Triple-negative breast cancer is an aggressive type of invasive breast cancer that accounts for about 15% of all breast cancers. It is a difficult cancer to treat.

What Are the Stages of Breast Cancer?

If you've been diagnosed with breast cancer, you’ll want to know what stage it is. The answers will help you and your doctors know more about what’s ahead and decide on your treatments.
Based on these findings, doctors string together letters and numbers to assign a stage to every case of breast cancer. It may seem like a strange code, but it’s really just a way to pinpoint exactly what’s going on with your cancer. Think of it like this: The longer the list of letters and numbers, the more exact the diagnosis and the more precise the treatment plan.
Stages of breast cancer


Breast Cancer Stages
The stages are the number zero and the Roman numerals I, II, III, or IV (often followed by A, B, or C). In general, the higher the number, the more advanced the cancer. But there’s more to it than that.






Stage 0. The cancer has been diagnosed early. It started in the breast ducts or milk glands and has stayed there. You’re likely to hear or see the words in situ, meaning “in the original place.”

Stage I. Starting at this level, breast cancer is called invasive, meaning it has broken free to attack healthy tissue.

Stage 1A means the cancer has spread into the fatty breast tissue. The tumor itself is no larger than a shelled peanut, or there may be no tumor

Stage IB means some cancer cells, but just tiny amounts, have been found in a few lymph nodes.

Stage II. The cancer has grown, spread, or both.

IIA means the tumor in the breast is still small, if there's one at all. There may be no cancer in the lymph nodes, or it may have spread to as many as three.

IIB breast tumor is bigger -- it may be the size of a walnut or as big as a lime. It may or may not be in any lymph nodes.

Stage III. The cancer has not spread to bones or organs, but it’s considered advanced, and it’s harder to fight.

IIIA means the cancer has been found in up to nine of the lymph nodes that form a chain from your underarm to your collarbone. Or it has spread to or enlarged the lymph nodes deep in your breast. In some cases there is a large tumor in the breast, but other times there’s no tumor.

IIIB means the tumor has grown into the chest wall or skin around your breast, even if it hasn’t spread to the lymph nodes.

IIIC means cancer has been found in 10 or more lymph nodes, or has spread above or below your collarbone. It’s also IIIC if fewer lymph nodes outside the breast are affected but those inside it are enlarged or cancerous.

Stage IV. Breast cancer cells have spread far away from the breast and lymph nodes right around it. The most common sites are the bones, lungs, liver, and brain. This stage is described as “metastatic,” meaning it has spread beyond the region of the body where it was first found.

TNM System for Breast Cancer
Doctors also group cancers by the letters T, N, or M. Each of those letters tells you something about your cancer.

“T” stands for tumor, or the lump of cancer found in the breast itself. The higher the number assigned after it, the bigger or wider the mass.

“N” stands for nodes, as in lymph nodes. These small filters are found throughout the body, and they're especially dense in and around the breast. 
“M” stands for metastasis. The cancer has spread beyond the breast and lymph nodes.

Awareness of breast Cancer

it is the common cancer in American women, except for skin cancers. The average risk of a woman in the U.S. developing breast cancer sometime in her life is about 12%, or a 1 in 8 chance. The chance that a woman will die from breast cancer is about 2.6%, or a 1 in 38 chance. The ACS estimates that about 41,760 women will die from breast cancer in 2019.
Today, there are more than 3.1 million breast cancer survivors in the U.S., including women still being treated and those who have finished treatment. “A heightened awareness of the disease has unquestionably led to a greater number of women being screened for breast cancer,” said Catherine Tuite, MD, Section Chief of Breast Radiology and Associate Professor of Diagnostic Imaging at Fox Chase Cancer Center. “Patients are experiencing better outcomes as a result of early diagnosis, state-of-the-art treatment options and less extensive surgery.”

Risk factors of breast cancer
risk factors for breast cancer

Risk factor refers to a certain predispose that increases your risk of developing breast cancer. Many of the most important risk factors for breast cancer are beyond your control, such as age, family history, and medical history. However, there are some risk factors you can control, such as weight, physical activity, and alcohol consumption.
Some of the risk factors you can't control include Gender, Age, Family history, race, pregnancy, and breastfeeding
Be sure to talk with your doctor about all of your possible risk factors for breast cancer. There may be steps you can take to lower your risk of breast cancer, and your doctor can help you come up with a plan.
Your doctor also needs to be aware of any other risk factors beyond your control, so that he or she has an accurate understanding of your level of breast cancer risk. This can influence recommendations about breast cancer screening — what tests to have and when to start having them.
