All to Know About Breast Cancer – It Might Save Lives

Breast cancer is a disease in which cells in the breast grow out of control. There are different kinds of breast cancer. The kind of breast cancer depends on which cells in the breast turn into cancer.

Breast cancer can begin in different parts of the breast. A breast is made up of three main parts: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. The ducts are tubes that carry milk to the nipple. The connective tissue (which consists of fibrous and fatty tissue) surrounds and holds everything together. Most breast cancers begin in the ducts or lobules.

Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.

Kinds of Breast Cancer

The most common kinds of breast cancer are—

Invasive ductal carcinoma.

The cancer cells begin in the ducts and then grow outside the ducts into other parts of the breast tissue. Invasive cancer cells can also spread, or metastasize, to other parts of the body.

Invasive lobular carcinoma. Cancer cells begin in the lobules and then spread from the lobules to the breast tissues that are close by. These invasive cancer cells can also spread to other parts of the body.

There are several other less common kinds of breast cancer, such as Paget’s disease, external icon medullary, mucinous, and inflammatory breast cancer.

Ductal carcinoma in situ (DCIS)

It is a breast disease that may lead to invasive breast cancer. The cancer cells are only in the lining of the ducts, and have not spread to other tissues in the breast.

What are the signs and symptoms of breast cancer?

There are many different signs and symptoms of breast cancer, so regularly checking your breasts for anything different or new is important.

The earlier breast cancer is diagnosed, the better the chance of successful treatment. Getting to know what your breasts look and feel like normally means it’s easier to spot any unusual changes and check them with your doctor. 

Common breast cancer signs and symptoms include:

  • lump or swelling in the breast, upper chest or armpit. You might feel the lump, but not see it.
  • Changes in the size or shape of the breast
  • change in skin texture i.e. puckering or dimpling of the skin
  • change in the colour of the breast – the breast may look red or inflamed
  • Rash, crusting or changes to the nipple
  • Any unusual discharge from either nipple

Over a third (39%) of women in the UK do not check their breasts regularly for potential signs of breast cancer.

According to a YouGov survey commissioned by Breast Cancer Now, a third (33%) of those who do check their breasts for possible signs and symptoms don’t feel confident that they would notice a change.

Asked what stops or prevents them from checking their breasts more regularly, over half (53%) forgetting to check, over a third (39%) not being in the habit of checking, a fifth (19%) not feeling confident in checking their breasts, not knowing how to check (16%), not knowing what to look for (12%) and being worried about finding a new or unusual change (11%). 

Checking your breasts only takes a few minutes. Everyone will have their own way of touching and looking for changes, but remember to check the whole breast area, including your upper chest and armpits.

There’s no special technique and you don’t need training. Find out more about the signs and symptoms of breast cancer.

What can cause breast cancer?

There are many different factors that can affect your chances of developing breast cancer. There’s no one single reason – it results from a combination of the way we live our lives, our genes and our surrounding environment.

What can I do to reduce my risk of breast cancer?

Everyone can take steps to lower their chances of getting breast cancer by making small healthy changes and living well now, including drinking less alcohol, maintaining a healthy weight and keeping physically active.

What breast cancer risk factors can’t I change?

Some factors are outside our control, including:

  • Being a woman – 99% of new cases of breast cancer are in women.
  • Getting older – 80% of breast cancers occur in women over the age of 50. Most men who get breast cancer are over 60.
  • A family history of breast cancer – if you have a family history of breast cancer, you and some other members of your family may have a higher than average risk of developing the disease, however, there may be some ways you can manage your risk.

How many people develop breast cancer?

  • Almost nine in ten (85%) of women survive breast cancer for five years or more.
  • Breast cancer survival is improving and has doubled in the past 40 years in the UK due to a combination of improvements in treatment and care, earlier detection through screening and a focus on targets, including faster diagnosis.
  • An estimated 600,000 people are alive in the UK after a diagnosis of breast cancer. This is predicted to rise to 1.2 million in 2030

What is secondary (or metastatic) breast cancer?

Secondary (or metastatic) breast cancer is when breast cancer spreads from the breast to other parts of the body, becoming incurable. Breast cancer most commonly spreads to the bones, brain, lungs or liver.

While it cannot be cured, there are treatments that can help control certain forms of the disease for some time and relieve symptoms to help people live well for as long as possible.

There are an estimated 35,000 people living with secondary breast cancer in the UK. In around 5% of women, breast cancer has already spread by the time it is diagnosed.

5 Little-Known Breast Cancer Facts

1. Breast cancer doesn’t always come in the form of a lump.

Breast cancer in its earliest stages usually doesn’t have any symptoms. When symptoms do appear, it’s not always in the form of a lump. Be on the lookout for any of the signs below and report them to your doctor right away.

  • Lump in your breast
  • Swelling in or around your breast, collarbone or armpit
  •  Skin thickening or redness in or around your breast
  • Breast warmth and itching
  • Nipple changes or discharge
  • Breast pain lasting for more than three to four weeks

2. Having a male relative who’s had breast cancer increases your chances.

You may be more likely to get breast cancer if you have a male relative who’s had the disease. This is especially true if it’s a close family member like a father, brother or son. If you fall in this group, talk to your doctor about genetic testing to find out if cancer runs in your family.

3. Maintaining a healthy weight can reduce your breast cancer risk.

Being overweight or obese — especially after menopause — may raise your cancer risks. To keep your cancer risk low, avoid weight gain by eating healthy foods and staying active. Stick with a plant-based diet rich in fruits, vegetables, whole grains and beans.  And, try to fit in at least 30 minutes of physical activity in your day.

4. You don’t need to learn how to do a self-exam.

Studies show that doing monthly breast self-exams isn’t necessary.

Instead, it’s more important to stay aware of how your breasts look and feel. If you notice changes, report them to your doctor without delay. This works just as well as doing a formal breast self-exam.

5. Drinking several glasses of alcohol a day can up your breast cancer risk.

Having a glass of wine now and again is not bad for your health. But, drinking several glasses a day can increase your breast cancer risk.

Play it safe by sticking to the recommended serving size. The American Institute for Cancer Research recommends that women have no more than one drink per day and men have no more than two drinks per day.
