Cáncer de Mama: Diagnóstico

Cáncer de Mama: Diagnóstico

• Mamografía: A radiographic imaging technique used to detect breast abnormalities. It is a primary screening tool for early detection of breast cancer.
• Ultrasonido: A non-invasive technique that uses sound waves to create images of the breast tissue. It is often used to distinguish between solid and fluid-filled masses.
• Resonancia magnética (RM): Utilizes powerful magnetic fields and radio waves to produce detailed images of the breast. It can be more beneficial in certain cases, such as women with dense breasts or those with a strong family history of breast cancer. May be used for diagnostic purposes or to guide procedures (biopsy).
• Biopsia: The removal of a tissue sample for microscopic examination. Essential to confirm a suspected cancer diagnosis. Different types exist (fine needle aspiration, core needle biopsy, surgical biopsy).
• Análisis de sangre: Blood tests are not used for a definitive cancer diagnosis , but may help assess overall health and detect possible markers (tumour markers) associated with malignancy.

Cáncer de Mama: Tratamientos

• Cirugía: Surgical removal of the tumor and surrounding tissue. Different types of surgery, including lumpectomy (partial removal) and mastectomy (complete removal).
• Radioterapia: Uses high-energy radiation to destroy cancer cells. Can be used as an adjuvant treatment after surgery or as a primary treatment for inoperable tumors.
• Quimioterapia: Use of drugs to kill or slow the growth of cancer cells. Systemic treatment that affects the entire body.
• Terapia hormonal: Used when the tumor is hormone-receptor positive. Aims to block the hormones in the body that stimulate the cancer cell growth.
• Terapia dirigida: Targets specific genetic or molecular abnormalities in cancer cells, leading to more precise treatment options reducing side effects on healthy cells.

Cáncer de Mama: Factores de Riesgo

• Edad: Risk increases with age. Post-menopausal women are more at risk.
• Antecedentes familiares: Strong family history of breast cancer, particularly in close relatives, significantly increases risk. Specific gene mutations (BRCA1 and BRCA2) are known risk factors.
• Antecedentes personales: Prior diagnosis of breast cancer or benign breast diseases, increase the chance of developing a new cancer in the future.
• Densidad mamaria: Greater breast density can make cancer more difficult to detect on mammograms.
• Menarquía temprana/Menopausia tardía: Early onset of menstruation and late menopause may increase the lifetime exposure to estrogen, a factor connected with breast cancer risk.
• Obesidad: Being overweight or obese after menopause is a risk factor.
• Inactividad física: A lack of physical activity can raise the risk.
• Consumo de alcohol: Moderate to high alcohol consumption has been associated with a higher risk.
• Antecedentes de cánceres reproductivos: Conditions like ovarian or uterine cancer may have associated higher risk.
• Otros: Certain medications, exposure to radiation, and/or environmental factors can contribute.

Cáncer de Mama: Prevención

• Detección temprana: Screening programs like regular mammograms help identify cancer early, when treatment is more effective.
• Mantenimineto de un peso saludable: Maintaining a healthy weight.
• Actividad física: Regular exercise.
• Alimentación saludable: A balanced diet.
• Limitación del consumo de alcohol: Reducing alcohol consumption.
• Limitar el consumo de grasas: A diet with limited saturated and trans fats.
• Ciertos medicamentos: Some medications have the potential to reduce risk, but use of any of them must be addressed in collaboration with healthcare professionals.

Cáncer de Mama: Concienciación

• Promover la detección temprana: It is important to encourage regular checkups.
• Educando sobre la prevención: Providing information about risk factors and ways to reduce them.
• Apoyo a los pacientes: Offering emotional support and information during treatment and recovery.
• Reducir el estigma: Working to decrease the social stigma associated with breast cancer.

Cáncer de Mama: Epidemiología

• Prevalencia Global: Breast cancer is one of the most common types of cancer in women worldwide.
• Tendencias en la incidencia: Changes in incidence rates across different populations and time periods.
• Factores demográficos: Age, ethnicity, and socioeconomic status may all be associated with the incidence and prevalence of breast cancer.
• Tasas de mortalidad: Analysis of the mortality rates, which can vary depending on stage and treatment.

Cáncer de Mama: Histología

• Tipos de cáncer de mama: Different histological types, like ductal carcinoma in situ or invasive ductal carcinoma. Specific characteristics can influence treatment strategies and prognosi.
• Grado de malignidad: Classification of the degree of aggressiveness (grading) of cancer cells.
• Receptores hormonales: Presence or absence of estrogen and progesterone receptors impacts treatment decisions.
• Receptores de Her2/neu: Presence or absence of these receptors are critical indicators as their presence often requires targeted treatments.

Cáncer de Mama: Estadificación

• TNM: System for staging breast cancers based on tumor size (T), lymph node involvement (N), and presence of metastasis (M). This assessment guides treatment planning and prognosis.
• Clasificación y significado clínico: Understanding each stage's implication in terms of the likelihood of recurrence or spread.
• Implicaciones para el tratamiento: Stage significantly impacts the approach, intensity, and type of treatment.
