ونجح فريق بحثي في الولايات المتحدة في تحديد بعض البروتينات الموجودة في سوائل الجسم التي يمكن استخدامها كدلالات للأورام وسرطان الثدي، ما يساعد في رصد سرطان الثدي مبكرا والبدء في رحلة العلاج في توقيت مناسب لزيادة فرص الشفاء.
وتقول الباحثة دانييل ويتهام المتخصصة في مجال الكيمياء الحيوية بجامعة كلاركسون الأميركية إن العلم الحديث يمكنه الآن تحليل البروتينات في مختلف أنسجة وسوائل الجسم مثل الدم واللعاب والبول والدموع وحليب الأم.
وأضافت في تصريحات للموقع الإلكتروني "ميديكال إكسبريس" المتخصص في الأبحاث الطبية أن عقد مقارنة بين البروتينات الموجودة في بعض سوائل الجسم لدى الاصحاء ولدى مريضات سرطان الثدي ساعد في اكتشاف فروقات معينة في طبيعة هذه البروتينات على نحو يتيح استخدامها كدلالات للكشف المبكر عن الاورام.
واوضحت ويتهام أن حليب الأم يحتوي على مواد بروتينية يتم إفرازها من الغدد اللبنية لدى الأم، وبالتالي فإن أي تغير في حليب الأم يعكس وجود مشكلة أو تغير في خلايا الثدي، مضيفة أن بعض البروتينات الموجودة في حليب الأم يمكن رصدها أيضا في الدم.
وأكدت أن رصد البروتينات التي تدل على الإصابة بالسرطان في الدم يتيح إمكانية فحص النساء في مختلف الفئات العمرية بصرف النظر عن أوضاعهم الإنجابية، وبالتالي لا يقتصر الاستفادة من هذه الدراسة العلمية على النساء المرضعات فقط.
