Breast cancer is the most common cancer in women, accounting for one in ten new cancer diagnoses annually. It is the second leading cause of cancer death among women worldwide. Anatomically, the milk-producing organs of the breast are situated in front of the pectoral wall. They are supported by the pectoralis major muscle and held in position by ligaments connecting the breast to the chest wall. The breast is composed of fifteen to twenty lobes that are circularly arranged.
The size and shape of the breasts are determined by the fat that covers the alveoli. Each lobe is composed of lobules, which, when stimulated by hormones, contain milk-producing glands. Breast cancer is an always-silent disease. The majority of patients with the disease are diagnosed through routine testing. Others may experience a breast tumor, a change in breast size or shape, or a discharge from the nipple.
Despite this, mastalgia is a prevalent condition. In order to diagnose breast cancer, a physical examination, imaging, specifically mammography, and a tissue sample are required. Early diagnosis increases the likelihood of survival. Due to the propensity of the tumor to disseminate lymphatically and hematologically, the prognosis is poor and distal metastases are present. This article highlights the significance of breast cancer screening activities.
The study of etiology
In women’s general health examinations, it is essential to identify breast cancer development risk factors.
Risk factors for breast cancer are divided into seven categories:
Age:
Even when risk factors are accounted for, the incidence of breast cancer continues to rise as the female population ages.
The vast majority of breast cancer patients are women.
A history of primary breast cancer increases the likelihood that the opposite breast will develop primary breast cancer.
Variables related to histologic danger: Histologic abnormalities detected during breast biopsies represent a wide range of breast cancer risk factors. These anomalies (LCIS) include proliferative alterations accompanied by atypia and lobular carcinoma in situ.
Due to genetic risk factors associated with their family history, first-degree relatives of breast cancer patients have a 2- to 3-fold increased risk of the disease. 5% to 10% of breast cancer cases may have hereditary causes, with genetic factors accounting for 25% of cases in women under 30. The two most common alleles associated with an increased risk of breast cancer are BRCA1 and BRCA2.
It is believed that reproductive milestones increase a woman’s lifetime oestrogen consumption, which may increase her risk of developing breast cancer. Menarche occurring before the age of 12, first live birth occurring after the age of 30, and menopause occurring after the age of 55 are examples of these conditions.
Progesterone and oestrogen are used both medically and as dietary supplements to address a variety of maladies. The two most common uses are contraception in premenopausal women and hormone replacement therapy in postmenopausal women.
Breast Cancer Therapy Management
Reducing the risk of metastatic dissemination and the possibility of a local recurrence are the two essential therapeutic concepts. Local cancer is controlled using surgery with or without radiotherapy.
Systemic therapy, which may include hormone therapy, chemotherapy, targeted therapy, or any combination thereof, is recommended when metastatic relapse is possible. Arimidex 1mg is used in postmenopausal women to treat breast cancer. The hormone oestrogen accelerates the development of certain breast malignancies.
Surgery and Breast Cancer Pills are the most prevalent breast cancer treatments. It is the most fundamental method of managing local diseases. Halsted’s radical mastectomy, in which the breast is removed along with axillary lymph node dissection and both pectoral muscles are removed, is no longer recommended due to its high morbidity risk and lack of survival benefit.

Patsy underwent a modified radical mastectomy, which is becoming increasingly common. The entire breast tissue must be removed, as well as a significant portion of axillary epidermis and lymph nodes. The primary and secondary pectoral muscles remain.
Oncologic radiation therapy
Radiation therapy has a significant impact on disease management at the local level. Radiation therapy administered after breast-conserving surgery reduces the risk of cancer recurrence by approximately 50% and the risk of breast cancer mortality by approximately 20% after 10 years. It has not been demonstrated that radiation therapy improves survival in patients who have received hormonal therapy for at least five years; therefore, radiation therapy is contraindicated in women 70 and older with small, lymph node-negative, hormone receptor-positive (HR+) tumours.
When a tumor is large (greater than 5 centimeters), has invaded the epidermis or chest wall, or has positive lymph nodes, radiation therapy is beneficial. In severe cases, such as those involving bone metastases or the central nervous system (CNS), it can also be utilized as a palliative treatment. Radiation therapy can be administered via brachytherapy, external beam radiation, or a combination of the two techniques.
Disease, Oncology
Systemic therapies that are used to treat breast cancer include chemotherapy, hormone therapy, and targeted therapy. A 6-month course of chemotherapy from the first generation, such as cyclophosphamide, methotrexate, and 5-fluorouracil (CMF), can reduce the risk of relapse by 25% over a 10- to 15-year period.
Recent breast cancer treatments include taxanes and anthracyclines (doxorubicin or epirubicin). The duration of adjuvant and neoadjuvant chemotherapy is between three and six months. In the first ten and fifteen years, tamoxifen as adjuvant therapy for early-stage HR+ breast cancer has been shown to reduce recurrence and mortality rates, respectively.
The prognosis for early breast cancer is surprisingly favorable. There is a 100% five-year survival rate for stages 0 and I. The 5-year survival rates for stages II and III breast cancer are approximately 93% and 72%, respectively. When the disease extends throughout the body, the prognosis drastically worsens. Only 22% of patients with stage IV breast cancer survive five years.
