What is Cancer?

Cancer is a condition in which some cells in the body grow out of control and spread to other parts of the body.

Cancer may begin practically anywhere in the billions of cells that make up the human body. Human cells normally expand and multiply (via a process known as cell division) to generate new cells as needed by the body. Cells die as they get old or injured, and new cells replace them.

This ordered process can sometimes break down, resulting in aberrant or damaged cells growing and multiplying when they shouldn’t. Tumors, which are masses of tissue, can grow from these cells. Tumors may or may not be malignant (benign).

The Different Types of Cancer

There are about 100 different forms of cancer.

Cancers are frequently called for the organs or tissues in which they develop. Lung cancer, for example, begins in the lungs, while brain cancer begins in the brain. Cancers can also be classified based on the type of cell that caused them, such as epithelial or squamous cells.

Doctors classify cancer into several categories based on where it starts. There are four primary forms of cancer:

1. Carcinomas

 

The skin or the tissue that covers the surface of internal organs and glands is where a carcinoma develops. Carcinomas are often solid tumors. Cancers of this class are the most frequent. Prostate cancer, breast cancer, lung cancer, and colorectal cancer are all examples of carcinomas.

2. Sarcomas

 

Sarcomas start in the body’s supporting and connecting tissues. Fat, muscles, nerves, tendons, joints, blood arteries, lymph vessels, cartilage, and bone can all form sarcomas.

3. Leukemias

 

Leukemia is a kind of blood cancer. When healthy blood cells begin to alter and expand uncontrolled, leukemia develops. Acute lymphocytic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, and chronic myeloid leukemia are the four primary kinds of leukemia.

4. Lymphomas

 

Lymphoma is a malignancy of the lymphatic system that starts in the lymph nodes. The lymphatic system is a system of tubes and glands that assists in the fight against infection. Hodgkin lymphoma and non-Hodgkin lymphoma are the two most common forms of lymphomas.

What is Breast Cancer?

Breast cancer is a sickness in which the cells of the breast proliferate uncontrollably. There are several types of breast cancer. The kind of breast cancer is determined by which cells in the breast develop into cancer.

Breast cancer can develop in a variety of locations within the breast. A breast is composed of three major components: lobules, ducts, and connective tissue. The glands that generate milk are known as lobules. 

Ducts are tubes that transport milk to the nipple. The connective tissue (fibrous and fatty tissue) surrounds and binds everything together. The majority of breast cancers start in the ducts or lobules.

Breast cancer can spread outside of the breast via blood and lymph arteries. Breast cancer is considered to have metastasized when it spreads to other portions of the body.

Except for skin cancers, breast cancer is the most frequent cancer among American women.

Breast cancer in the United States Statistics shows that one in every eight women in the United States (13%) may get invasive breast cancer over her lifetime.

A projected 281,550 new instances of invasive breast cancer will be identified in women in the United States in 2021. Along with 49,290 new cases of non-invasive (in situ) breast cancer.

In 2021, around 2,650 new instances of invasive breast cancer in males are predicted to be diagnosed. A man’s lifetime chance of developing breast cancer is around 1 in 833.

Breast cancer is estimated to kill 43,600 people in the United States in 2021. Since 2007, death rates for women under the age of 50 have remained stable, while rates for women over the age of 50 have continued to fall.

From 2013 to 2018, the total mortality rate from breast cancer fell by 1% every year. These reductions are assumed to be the consequence of advancements in therapy and earlier discovery through screening.

Breast cancer is the leading cause of mortality among women in the United States, surpassing all other cancers except lung cancer.

Symptoms of Breast Cancer:

The American Cancer Society states that any of the following unexpected changes in the breast can be a sign of breast cancer:

  • Swelling of the whole or a portion of the breast,
  • Skin irritation, or dimpling breast discomfort
  • Nipple discomfort or inward nipple redness, scaliness, or thickness of the nipple or breast skin
  • A nipple discharge other than breast milk
  • An underarm lump
  • Any alteration in the breast’s size or contour.
  • Any part of the breast might be painful.

These changes may also be symptoms of less serious, non-cancerous illnesses, such as an infection or a cyst. Again, it’s critical to have any breast changes evaluated by a doctor as soon as possible.

Breast self-examination

It should be part of your monthly health care regimen, and you should see your doctor if you notice any changes in your breasts. 

If you are above the age of 40 or have a high risk of breast cancer, you should also get yearly mammography and physical exam performed by a doctor. The earlier breast cancer is discovered and diagnosed, the greater your chances of survival.

The actual diagnosing procedure might take weeks and involve a variety of tests. Waiting for results might feel interminable. 

The unpredictability stinks. However, if you comprehend your own unique “big picture,” you will be able to make better selections. You and your physicians can create a treatment plan that is unique to you.

What are the types of Breast Cancer?

1. Ductal Carcinoma In Situ (DCIS)

One in every five new cases of breast cancer will be ductal carcinoma in situ (DCIS). Almost of women with early-stage breast cancer may be cured.

DCIS can also be referred to as intraductal carcinoma or stage 0 breast cancer. DCIS is a kind of breast cancer that is non-invasive or pre-invasive. This suggests that the cells lining the ducts have transformed into cancer cells, but they have not migrated through the duct walls into surrounding breast tissue.
Because DCIS has not expanded into the surrounding breast tissue, it cannot spread (metastasize) to other parts of the body.

DCIS, on the other hand, can occasionally progress to aggressive malignancy. At that point, cancer had progressed from the duct into adjacent tissue and might have spread to other sections of the body.

A woman with DCIS can usually choose between breast-conserving surgery (BCS) and straightforward mastectomy. A woman with DCIS can usually choose between breast-conserving surgery (BCS) and a straightforward mastectomy.

2. Invasive Breast Cancer (IDC/ILC)

nvasive breast cancer refers to malignancies that have migrated into surrounding breast tissue.

The majority of breast cancers are invasive, although there are many forms of invasive breast cancer. Invasive ductal carcinoma and invasive lobular carcinoma are the two most prevalent types.

IDC Invasive ductal Carcinoma:

This is the most prevalent kind of breast cancer. Invasive (or infiltrating) ductal carcinomas account for approximately 8 out of 10 invasive breast cancers (IDC).

IDC begins in the cells that border the breast milk duct. The malignancy then bursts through the duct wall and spreads to the adjacent breast tissues. It may be able to spread (metastasize) to other regions of the body through the lymph system and circulation at this stage.

ILC Invasive Lobular Carcinoma: 

Invasive lobular carcinoma accounts for approximately one-tenth of all invasive breast malignancies (ILC).

ILC begins in the glands that produce milk (lobules). It, like IDC, can spread (metastasize) to other regions of the body. On physical examination and imaging, such as mammograms, invasive lobular carcinoma may be more difficult to detect than invasive ductal carcinoma. 

In addition, compared to other types of invasive carcinoma, about 1 in 5 women with ILC may have cancer in both breasts.

Treatment for invasive breast cancer is determined by the stage of the tumor and other variables. The majority of women will require surgery to remove the tumor. Depending on the kind of breast cancer and how advanced it is, you may require further therapy before or after surgery or both.

3. Triple-Negative Breast Cancer

Triple-negative breast cancer (TNBC) accounts for around 10-15% of all breast cancers. 

The term triple-negative breast cancer refers to cancer cells that lack estrogen and progesterone receptors as well as a high level of the protein HER2. (All three tests result in “negative” results for the cells.) These malignancies are more frequent in women under the age of 40, African Americans, and those with a BRCA1 mutation.

Triple-negative breast cancer is distinct from other forms of invasive breast cancer in that it grows and spreads more quickly, has fewer treatment choices, and has a poor prognosis.

There are fewer therapy choices for triple-negative breast cancer than for other kinds of invasive breast cancer. Surgery is a possibility if cancer has not progressed to other parts of the body. 

Chemotherapy may be used initially to reduce a big tumor before surgery. It may also be administered after surgery to lessen the likelihood of the cancer returning. Depending on the characteristics of the tumor, radiation may potentially be a therapeutic possibility.

4. Inflammatory Breast Cancer (IBC)

Inflammatory breast cancer (IBC) is uncommon, accounting for just 1% to 5% of all breast cancers. 

Although it is frequently classified as invasive ductal carcinoma, it varies from other forms of breast cancer in terms of symptoms, prognosis, and therapy. 

IBC has inflammatory signs such as swelling and redness, although infection or damage do not cause IBC or the symptoms. IBC symptoms are produced by cancer cells obstructing lymph veins in the skin, giving the breast an “inflamed” appearance.

Preventive methods of Breast Cancer:

1. Physical exercise:

 

Many studies have indicated that moderate to vigorous physical activity is associated with a decreased risk of breast cancer, thus it’s critical to receive regular physical activity. 

The American Cancer Society advises that individuals engage in at least 150 to 300 minutes of moderate-intensity activity or 75 to 150 minutes of vigorous-intensity activity each week (or a mix of these), preferably spaced out for the week. It is excellent to reach or exceed the top limit of 300 minutes.

2. Maintain a healthy weight:

 

Both increasing body weight and weight growth as an adult have been associated with an increased risk of breast cancer after menopause. The American Cancer Society suggests that you maintain a healthy weight throughout your life by combining your food consumption with physical exercise.

3. Avoid or restrict alcohol consumption:

 

Alcohol raises the risk of breast cancer. Even moderate alcohol use has been related to an increase in risk. 

It is advised not to consume alcohol. Women who do drink should limit themselves to one alcoholic drink each day. A drink is defined as 12 oz. of beer, 5 oz. of wine, or 1.5 oz. of 80-proof distilled spirits (hard liquor).

4. Lowering the risk through nutrition:

 

Some studies show that a diet heavy in vegetables, fruit, and calcium-rich dairy products, but low in red and processed meats, may help decrease the risk of breast cancer. 

It’s also unclear if certain veggies, fruits, or other meals might reduce risk. Furthermore, most studies have concluded that a reducing fat diet does not influence breast cancer risk (although some have suggested it might help lower the risk of dying from breast cancer).

5. Minimize Hormone treatment for postmenopausal:

 

women’s breast cancer risk may be increased by using a combination of hormones. Discuss the advantages and disadvantages of hormone treatment with your doctor.

Some women endure uncomfortable signs and symptoms throughout menopause, and the higher risk of breast cancer may be acceptable to these women in exchange for relief from menopausal symptoms.

Use the smallest dose of hormone treatment for the shortest period to lower the risk of breast cancer.

6. Extend Breastfeeding period:

 

When a woman breastfeeds, she undergoes hormonal changes that may cause her menstrual periods to resume later. This lowers her lifelong exposure to hormones like estrogen, which have been associated to an increased risk of breast and ovarian cancer.

A longer period of breastfeeding is connected with maternal illness reduction and protection, according to the Academy of Breastfeeding Medicine (ABM). According to the ABM, it lowers the risk of breast cancer, ovarian cancer, diabetes, hypertension, obesity, and heart attack.

Early detection of breast cancer minimises the risk of dying from the disease. When breast cancer is detected early, it is significantly easier to treat and has a substantially higher chance of survival. 

As a result, frequent screenings are an essential element of women’s healthcare. Let’s be aware and create a Cancer free US.
