Breast Cancer: Symptoms, Causes and Treatment
Breast cancer is one of the most common cancers found in women around the world. It can be referred to as a malignant growth often caused by abnormal cell multiplication within the tissue of the breast, which leads to the formation of tumours. While mostly found in females, breast cancer also exists in males. Early detection through screening and awareness of symptoms is important as it significantly enhances the chances of survival and improves treatment.
What is Breast Cancer?
Breast cancer is a cancerous condition of the breast by which cells multiply uncontrollably within the breast tissue. It may originate from any of the different components of the breast, including lobules, which are the milk-producing glands, and ducts, which carry milk. Of all breast tumours, most are benign; however, some become malignant, invade tissues in the immediate vicinity or the rest of the body, and thus represent invasive cancer of the breast.
What are the Symptoms of Breast Cancer?
Early detection of breast cancer will help better the outcome. The following are the symptoms one must be aware of.
- Changes in Breast Shape or Size
The most general symptom is a change in the size or shape of one or both breasts. This happens suddenly, and pain does not necessarily occur along with it.
- Lump or Mass in the Breast
It often includes a lump or mass on the breast as the first sign of breast cancer. Not all lumps are cancerous; however, any new lump should be looked at by a healthcare provider.
- Skin Changes
Breast cancer can affect the appearance of the skin of the breast. Dimpling, puckering, or a rash can occur. Sometimes, the skin may be swollen or even look like an orange peel.
- Changes in the nipples
The nipple may change, for example, inversion, which is when it turns inward, or discharge, especially if it contains blood or fluid. Any change in the nipple should be taken to a healthcare provider.
- Pain in the Breast or Nipple
While breast cancer is rarely painful in its early stages, some women will find that they have discomfort or pain in the breast or nipple area.
- Swelling in the Breast or Axilla
There can be swelling in the breast or axilla resulting from breast cancer. The swelling may not be painful.
- Changes in Breast Tissue
Cancer of the breast causes changes in the tissue texture of the breast that can appear as thickening or as hard areas.
What Causes Breast Cancer?
These causes of breast cancer may provide a clue to risk factors, which subsequently may lead to preventive measures. Even though no one knows the exact cause, some risk factors have been established to contribute to the generation of the disease.
- Genetic Factors
Genetic causes of breast cancer include inherited factors. Genes may be inherited when various mutations occur in the human body. In this case, genes like BRCA1 and BRCA2 increase the likelihood of developing cancerous changes in the breasts. Therefore, women with a family history of breast cancer should seek a genetic counsellor or be tested.
- Hormonal Factors
Coning into that, hormones play a great role in the development of breast cancer. Women who experience early menstruation or those who experience menopause when they are older may have increased risks due to the long exposure periods to estrogen.
- Age
Age is a significant risk factor for breast cancer. The cases occur usually in women who are older than 50 years.
- Lifestyle Choices
Some lifestyle factors raise the risks of breast cancer. Indicators such as obesity and less physical activity seem to be highly related to increased risks.
- Radiation Exposure
The radiation exposure would increase the risk of developing breast cancer especially medical treatment for other cancers.
- Reproductive History
A woman’s reproductive history can influence her risk. Women who have never been pregnant or had a first birth after age 30 are believed to be at higher risk than others for breast cancer.
- Environmental Factors
Although research is ongoing, some studies indicate that exposure to certain chemicals and toxins might increase the risk of developing breast cancer.
How Is Breast Cancer Diagnosed?
Early detection would determine whether proper treatment was possible. There are several diagnostic procedures for breast cancer, which include:
- Clinical Breast Examination
The health care provider makes a physical check for lumps or any abnormality in breast tissue.
- Mammography
Mammograms are X-ray images of the breast and are often an important screening method for finding early cancers in the breast. Generally, women are advised to begin regular mammograms at age 40, although this might differ for each individual due to various risk factors.
- Ultrasound
Breast ultrasound can be used when there is an apparent abnormality detected by a mammogram or a physical examination.
- Biopsy
If there is any lump or suspicious region, a biopsy can be carried out to find cancerous cells. That is the withdrawal of a small sample of breast tissue for examination.
- MRI
In some cases, an MRI or Magnetic Resonance Imaging may be performed in the following situations, especially in women who are at risk of having breast cancer.
What are the treatments for breast cancer?
The treatment of breast cancer, depending upon stages of cancer, type of breast cancer, as well as the general health of the patient, is based on a variety of considerations. The following are the most important treatments:
- Surgery
Surgery frequently constitutes major treatment for breast cancer and can be a single or multiple treatment, including:
- Lumpectomy: It is known as the removal of the tumour along with a small area of surrounding tissue. It is then followed by radiation therapy, which is often very frequent.
- Mastectomy: Removing of partially or both breasts. The treatment is sometimes recommended for patients having a greater risk of higher advancement and hereditary kind of cancer.
- Radiation Therapy
Radiation therapy makes use of high-energy waves that kill cancer cells by targeting them. Most of the time follows surgery to remove any remaining cancer cells.
- Chemotherapy
Chemotherapy involves killing or slowing the cancerous cells by using medications. Sometimes, it may be used neoadjuvantly - that is before surgery so that the tumor size is reduced, and sometimes as adjuvant therapy after surgery so that the chances of recurrence of the disease are reduced.
- Hormone Therapy
Hormone therapy may be helpful in hormone receptor-positive cancers. Here, the body's natural hormones that else will promote the growth of cancer cells are restrained from doing so.
- Targeted Therapy
Targeted therapies are some of the newest types of treatments that target the characteristics of cancer cells. In the case of HER2-positive breast cancer, for example, drugs can be used that target the HER2 protein.
- Immunotherapy
Immunotherapy is a treatment that lets the body's immune system fight cancer by helping it find or focus on the cancerous cells. The application of this method is still in research for breast cancer but has shown so much promise, especially in the case of triple-negative breast cancer.
How Can Breast Cancer Be Prevented?
Although no one can influence the chance of whether or not they get breast cancer, certain lifestyle changes and strategies lower the risk:
- Screening Regularly
Routine mammograms and clinical exams enable early detection and effective treatment of breast cancer.
- Healthy Lifestyle Choices
Maintaining a healthy weight, exercising, and reducing alcohol intake are among the ways of preventing breast cancer.
- Genetic Testing
In some cases, having a family history of breast cancer, the outcome of genetic testing may be used to determine one's level of risk, and thus, they may be able to undertake preventive measures, such as prophylactic surgery or closer monitoring.
- Drugs
For women with high-risk profiles, prescription drugs like SERMs, are a class of drugs that bind to estrogen receptors in the breast tissue but with very weak estrogen-like effects. This can also reduce the chances of getting breast cancer. Aromatase inhibitors could also do this.
What is the Outlook for Breast Cancer?
Usually, the prognosis depends on several factors; therefore, if it's type and stage at diagnosis. Targeted therapies and immunotherapies are also very helpful. Advanced-stage cases, early-stage breast cancer can also be cured, and even nowadays it's possible to prevent the advancement of the illness through follow-up, proper lifestyle, and treatment adherence.
Regular mammograms and other check-ups facilitate an early diagnosis. Every female should discuss her risk factors with our doctor at the Royal Medical Center to develop a proper screening schedule.
