Breast cancer screening methods start with manual palpation to check for lumps. Second, mammography is used, which is the most effective method for early diagnosis of breast cancer with a sensitivity of 80%-90%. Additionally, breast ultrasound and B-ultrasound examinations can be performed, which are simple, safe, and non-invasive. Another available method is breast MRI, which provides more accurate differentiation between benign and malignant tumors. Lastly, a biopsy using a hollow needle can also be done.

Breast cancer surgery accompaniment for a few days

The duration of postoperative care for breast cancer surgery depends on the extent of the surgery. This includes modified radical mastectomy, classic radical mastectomy, and surgeries that preserve both the breast and the axilla. For surgeries that preserve the breast and axilla, patients typically recover quickly, and generally, providing care for three to five days is more than sufficient. However, to ensure patients feel comforted and cared for, it's common to provide care starting the day before surgery until the patient is discharged. Postoperative care tends to be longer for modified radical mastectomies that include axillary clearance, as care is needed until the patient can fully manage the arm on the operated side on their own. Therefore, the care duration varies depending on the individual and their recovery. Thus, the shortest duration of care is usually for surgeries that preserve both the breast and axilla, typically sufficient within three to five days.

What is invasive breast cancer?

Invasive breast cancer is the most common tumor in women, accounting for 22% of all malignant tumors in females. Invasive breast cancer refers to a malignant tumor where cancer cells have broken through the basement membrane of the breast ducts or lobular alveoli and invaded the interstitium. The vast majority of invasive breast cancers are adenocarcinomas, originating from the epithelial cells of the breast parenchyma, especially from the terminal duct lobular units. Its characteristics include the tumor's infiltration into adjacent tissues and a marked tendency for distant metastasis.

How does one get breast cancer?

How is breast cancer caused? Regarding the causes of breast cancer, the primary factor should be family history. If a first-degree relative has breast cancer, then the likelihood of developing breast cancer increases. The second factor is reproductive factors; for instance, if the age at menarche is quite young, menopause age is relatively late, menstrual cycles are short, there is no childbirth or the age at first full-term pregnancy is older, there are fewer childbirths, and there is a lack of breastfeeding, then the incidence of breast cancer is also higher. The third factor involves hormones, possibly related to endogenous hormones or exogenous hormones, such as those mainly associated with oral contraceptives used externally. The fourth major point is a high-fat diet, or habits like drinking alcohol, smoking, and a diet low in vitamins, which may increase the risk of breast cancer. The fifth point involves other factors, such as exposure to significant amounts of ionizing radiation, chemicals from cancer drugs, lack of physical exercise, and occupations, such as working in the beauty industry or pharmaceutical manufacturing, etc., which may also increase the chances of developing breast cancer.

Symptoms of breast cancer metastasis

Symptoms of breast cancer metastasis first involve the lymph nodes, with multiple enlarged lymph nodes that can be felt beneath and above the collarbone. These can be diagnosed as metastases from breast cancer using color Doppler ultrasound and cytopathology puncture. The second symptom is bone metastasis. If there is pain in the pelvic or rib area, and an increase in alkaline phosphatase in the blood biochemistry, high suspicion of bone metastasis should be considered. It is necessary to conduct a PADCT or bone scan for further confirmation. If symptoms like coughing, expectorating phlegm, and blood-tinged sputum appear, lung metastasis should be considered, requiring further diagnosis with a CT scan.

Differences between Breast Hyperplasia and Breast Cancer

Both breast hyperplasia and breast cancer can present as breast lumps. The lumps in breast hyperplasia are generally softer or of medium hardness, often occurring bilaterally with multiple lumps of varying sizes. They may appear nodular, plaque-like, or granular, are quite mobile, and have no adhesion to surrounding tissues. The size and characteristics of the lumps commonly change with the menstrual cycle and emotional fluctuations, and they tend to grow slowly, predominantly affecting young and middle-aged women. In contrast, breast cancer lumps are generally harder, usually unilateral and solitary. These lumps may be round, oval, or irregular in shape, can grow quite large, have limited mobility, and tend to adhere to the skin and surrounding tissues. The lumps are not related to the menstrual cycle or emotional changes, can increase in size rapidly over a short period, and are more commonly seen in middle-aged and older women. Sometimes breast cancer can be confused with breast hyperplasia, necessitating a hospital visit for examination and diagnostic differentiation by a doctor.
