What is Breast Cancer?
Breast cancer can be found in tissues that line the breast ducts (epithelium) (85 percent) ,
and within the lobules (15 percent) of the breast glandular tissues.
At first, cancerous cells are restricted to the ducts and the lobules,
and are usually not symptomatic and with a low chance of expanding (metastasizing).
In time, these in situ (stage zero) cancer cells can eventually develop and invade parts of breast (invasive breast cancer)
and later grow to distant lymph nodes (specific local metastases) or to other organs of the body ( distant metastasis).
If a woman dies from the breast cancer it’s due to Spreading metastases.
The treatment for breast cancer can be highly effective, particularly when it is discovered in the early stages.
Treatment for breast cancer generally requires a combination of
- surgical treatment,
- radiotherapy and
- (hormonal treatment, chemotherapy or specific biological therapies)
to treat cancers that are small which spread through the tumor via the bloodstream. The treatment can save lives by stopping the spread and growth of cancerous tumors.
Breast Cancer Stats
In the year 2020, 2.3 million women worldwide were diagnosed with breast cancer, and 850,000 passed away.
In the year 2020, at the time of the last count the number of 7.8 million women alive were identified with cancer of the breast within the last five years,
which makes it the most frequent cancer around the globe.
Women worldwide are more likely to lose their disability-adjusted years due to breast cancer than other cancer.
Women from every nation around the globe develop the disease at whatever time following puberty,
but the rate of incidence rises in later the years of life.
The mortality rate of breast cancer has decreased between the 1930s and the 1970s.
Improvements in survival were evident in the 1980s,
when nations began to integrate early detection programs with various methods of treatment to treat the disease.
Who are at risk of Breast Cancer?
The breast cancer itself isn’t an infectious illness.
Contrary to some cancers that are associated with infection, for instance cervical cancers,
there aren’t identified bacterial and viral diseases that are associated with the development of breast cancer.
The majority of breast cancers affect women who have no known characteristics that could be considered risk factors,
other than being of the same gender (female) or older (over forty).
Certain conditions increase the risk of developing breast cancer, such as an increase in age and obesity,
the harmful consumption of alcohol and the history of family members with breast cancer radiation exposure,
history of reproductive issues (such as the age at the onset of menstrual cycle and age at the first pregnancy) smoking cigarettes, and postmenopausal hormone treatment.
The use of behavioral and other actions to decrease the risk of breast cancer include:
- long-term breastfeeding;
- Regularly exercise;
- Control of weight;
- Do not drink alcohol in a way that is harmful;
- Avoid exposure to smoke from cigarettes;
- Beware of long-term use of hormones Also, avoid long-term use of hormones.
- Beware of radiation exposure that exceeds your limits.
However, even if you control for any risk factors that are modifiable will not reduce the risk of breast cancer by 30%..
The gender of a woman is the most significant the risk of breast cancer.
The risk ranges from 0.5 percent to 1percent of breast cancers happen in males. The treatment for men with breast cancer must be based on the same rules that women do.
An ancestor’s history with breast cancer can increase the risk of developing breast cancer, however the majority of women who are diagnosed with breast cancer do not have a known history of family members with breast cancer. A lack of family history doesn’t necessarily suggest that a woman has an increased risk of developing breast cancer.
Certain genetically inherited “high penetrance” genetic mutations dramatically increase the risk of breast cancer particularly changes in BRCA1, BRCA2, and PALB-2 genes.
Women who have mutations in these important genes might consider strategies to reduce risk like the surgical removal of both breasts.
The patients who consider this highly insidious method are only a tiny number of women. should be thoroughly evaluated and all options should be considered and shouldn’t be taken lightly.
Signs and symptoms of Breast Cancer
The most frequent manifestation for breast cancer can be a non-painful lump or a thickening of the breast.
It is important to note that women who spot an abnormal breast lump even if there’s no discomfort and seek medical attention right away and without delay for more than one to two months.
A visit to a doctor at the first sign of symptoms will result in more effective treatment.
The most common symptoms of breast cancer may include:
- Thickenings or lumps on your breasts
- variations in the size, shape, or appearance
- Skin redness, pitting and pitting variations;
- The shape of the nipple, or the skin surrounding the area of the nipple (areola) or
- Atypical discharge from the nupple.
Breast lumps can be caused by different reasons, many of which aren’t cancerous. About 90 percent of breast lumps not cancerous. The benign breast lumps are lumps like fibroadenomas or cysts, and infections.
Breast cancer can take different types, which is the reason an extensive medical exam is essential.
Patients with persistent breast anomalies (usually lasting longer than 1 month) are advised to undergo an examination that includes breast imaging ,
and in certain cases biopsy of the tissue (biopsy) in order to establish if the lump has malignancy (malignancy) or benign.
The advanced cancer can cause damage to the skin, leading to opening wounds (ulcers) which aren’t necessarily painful.
Breast wounds that are not healing need to undergo an ultrasound.
Breast cancer may expand to other parts of the body, causing various symptoms.
Most of the time, though there may be lymph node malignancies that are not able to be identified however,
the most frequent site of growth that is first detected are the lymph nodes beneath the arm.
As time passes malignant tumors can grow to other organs, such as the liver, lungs, bones, and brain.
Once they have reached these regions there are new signs of cancer, like bone pain or headaches could develop.
Treatment For Breast Cancer
The treatment for breast cancer is highly efficient with the survival rate of 90 percent or higher, especially if the disease is detected in the early stages.
Treatment generally involves radiation therapy and surgery (local prevention) to treat the disease in the lymph nodes, breasts and the surrounding regions and the systemic treatment (oral and intravenous cancer medications) to control and/or decrease the chance of cancer spread (metastasizing).
Anticancer medicines comprise hormone (hormonal) therapychemotherapy, as well as in certain cases specifically targeted therapy (antibody).
In the past the past, breast cancers of all kinds were surgically treated using the mastectomy (complete surgical removal of the breast).
If the tumor is massive, mastectomy might be necessary.
Today, the majority of types of breast cancer can be dealt with using the smaller procedure known as lumpectomy, or a partial mastectomy. In this procedure, only the cancer is removed from the breast.
In this scenario treatment with radiation for the breast is generally necessary to decrease the possibility of recurrence within the breast.
When undergoing cancer surgery for aggressive malignancies, lymph nodes must be removed.
The past was when the removal of the lymph nodes in the axillary region (complete excision of lymph nodes of the axillary area) was believed to be essential to avoid the spreading cancerous tumors.
Nowadays, a procedure to remove smaller lymph nodes, referred to as”sentinel lymph node biopsy “sentinel lymph node biopsy” is more well-known because it’s less complicated.
The procedure uses stained tracers and/or radiotracers to search for the lymph nodes that are in the beginning in which cancer could have spread out of the breast.
The treatment for breast cancer may be administered prior to surgical procedures (“neoadjuvant treatment”) or following the procedure (“adjuvant treatment”) in accordance with the type of biological cancer.
aromatase inhibitors or tamoxifen.
Tumors with estrogen receptor (ER) or progesterone receptor (PR) could respond to the endocrine (hormonal) treatment such as aromatase inhibitors or tamoxifen.
Injecting these drugs for 5-10 years can reduce the likelihood of recurrence for these “hormone-positive” cancers by almost half. The treatment can cause menopausal symptoms, but it is generally tolerated.
Malignant tumors that are not able to have the hormone progesterone receptor or estrogen receptors.
These tumors can be classified “hormone receptor positive” and therefore require chemotherapy, regardless of whether the malignancy is small.
The current chemotherapy treatments are extremely efficient in reducing the likelihood of cancer cells growing or recurring, typically for outpatient treatments.
If there aren’t any complications, treatment for breast cancer typically is not a requirement for hospitalization.
Breast cancers could exude a molecule called HER-2/neu oncogene. The “HER-2 positive” malignancies can be controlled by targeted biologics, such as trastuzumab.
These biologics are extremely efficient, but they can be expensive since they are not chemical substances.
In the case of targeted biotherapies used they have the ability of eliminating cancerous cells when they are combined with chemotherapy.
The radiation therapy plays a significant part in treating breast cancer.
- In the case of early breast cancer the treatment of radiation can save women from needing the mastectomy.
- In the case of cancers with advanced stages the treatment can lower the chance of recurrence of cancer following a mastectomy is completed.
- In the case of advanced breast cancer In some instances radiation therapy may reduce the chance of being diagnosed with the disease.
The efficacy of breast cancer treatment is contingent on the complete treatment procedure. The use of topical treatments is not likely to result in positive results.
