    بالتأكيد، سأكون سعيدًا بمناقشة عوامل الخطر المختلفة المرتبطة بسرطان الثدي. العمر: يزداد خطر الإصابة بسرطان الثدي مع تقدم العمر. غالبية حالات سرطان الثدي تحدث لدى النساء فوق سن الخمسين. تاريخ العائلة:  الأفراد الذين لديهم أقارب مقربين (مثل الأم أو الأخت أو الابنة) الذين أصيبوا بسرطان الثدي هم أكثر عرضة للخطر. ويزداد هذا الخطر بشكل أكبر إذا أصيب قريب مصاب بسرطان الثدي في سن مبكرة أو إذا أصيب العديد من https://breastcancerpathology.universeconferences.com/registration/ الأقارب المقربين. الطفرات الجينية (BRCA1/BRCA2):   الطفرات في جينات BRCA1 وBRCA2 تزيد بشكل كبير من خطر الإصابة بسرطان الثدي والمبيض. تنتج هذه الجينات عادةً بروتينات تساعد على تثبيط نمو الخلايا وإصلاح الحمض النووي. وعندما تتحور هذه الخلايا، يرتفع خطر نمو الخلايا غير المنضبط وتطور السرطان. التعرض للإستروجين:  التعرض لفترات طويلة لهرمون الاستروجين هو عامل خطر. يمكن أن يكون هذا بسبب عوامل مثل بداية الدورة الشهرية المبكرة (قبل سن 12 عامًا) ، بداية انقطاع الطمث المتأخر (بعد سن 55) ، أو استخ...

  Precision Medicine and Targeted Therapies: These therapies focus on specific genetic or molecular abnormalities present in cancer cells. They aim to target these abnormalities with drugs, which can lead to more efficient tumor control with fewer side effects compared to traditional treatments. Immunotherapy: As mentioned earlier, immunotherapy is a ground-breaking approach that harnesses the body's own immune system to recognize and attack cancer cells. This has shown remarkable success in various types of cancer, including some forms of breast cancer. CAR-T Cell Therapy: This is a form of immunotherapy where a patient's T cells (a type of immune cell) are engineered to express chimeric antigen receptors (CARs) that target specific proteins in cancer cells. These modified T cells are then infused back into the patient, where they can recognize and attack cancer cells. Radio embolization and Radiotherapy Techniques: These techniques use targeted radiation to destroy ca...

  Ductal Carcinoma In Situ (DCIS), süt kanallarının iç yüzeyinde anormal hücrelerin bulunduğu ancak çevre dokulara yayılmadığı bir tür pre-invaziv meme kanseridir. "In situ" terimi, Latince kökenli olup "yerinde" anlamına gelir ve kanser hücrelerinin bulunduğu bölgeyi sınırlar. Bununla DCIS , genellikle mamografiler sırasında saptanır ve çoğu durumda belirli semptomlara yol açmaz. Bununla birlikte, ilerleyen safhalarda invaziv meme kanserine dönüşebilme potansiyeline sahiptir. Bu nedenle, erken teşhis ve tedavi önemlidir. DCIS teşhisi konduğunda, tedavi yaklaşımı genellikle şunları içerebilir: Cerrahi Girişimler : DCIS vakalarının çoğunda cerrahi müdahale gereklidir. Bu, genellikle lumpektomi olarak adlandırılan bir işlemi içerebilir. Lumpektomi, sadece anormal hücreleri içeren bölgenin çıkarılması anlamına gelir. Radyoterapi : Lumpektomi sonrası radyoterapi önerilebilir . Bu, meme dokusundaki olası kanser hücrelerinin yok edilmesine yardımcı olabilir....

  Track 20: Occupational and Safety Health :- Introduction:- A multidisciplinary field concerned with the safety, health, and welfare of individuals at work is known as occupational safety and health (OSH), also known as occupational health and safety (OHS), occupational health, or occupational safety (i.e. in an occupation). These terms initially served as an acronym for occupational safety and health program/department/etc. since they also allude to the field's objectives. Fostering a safe and healthy work environment is the aim of an occupational safety and health programme. All members of the general public who might be impacted by the workplace environment are likewise protected by OSH. An accident or illness related to the workplace claims the lives of more than 2.78 million people worldwide each year, or one every fifteen seconds. Every year, there are an extra 374 million nonfatal workplace accidents. According to estimates, the annual economic cost of occupationa...
