Can body odours point to Alzheimer's, cancer and other diseases?

کیا جسم کی بو الزائمر، کینسر اور دیگر بیماریوں کی نشاندہی کر سکتی ہے؟

क्या शरीर की गंध अल्ज़ाइमर, कैंसर और अन्य बीमारियों का संकेत दे सकती है?

Can body odours point to Alzheimer's, cancer and other diseases?

Key points

मुख्य बातें

  • Scientists have long explored whether molecules given off in breath, skin and urine could reveal disease, an idea going back to Hippocrates in the 5th century BC.
  • With new sensors that detect tiny amounts of molecules and advances in machine learning, non-invasive breath or urine tests now look closer to the clinic.
  • Studies have found breath compounds linked to lung cancer, a six-molecule urine panel that detected prostate cancer in 75 percent of cases, and a bladder-cancer urine test that won US Food and Drug Administration breakthrough designation in 2026, with an Alzheimer's version also designated in May.
  • سائنسدان طویل عرصے سے اس بات کی تحقیق کر رہے ہیں کہ سانس، جلد اور پیشاب سے نکلنے والے مالیکیول بیماری کی نشاندہی کر سکتے ہیں یا نہیں، یہ خیال پانچویں صدی قبل مسیح میں ہیپوکریٹس تک جاتا ہے۔ مالیکیول کی معمولی مقدار پکڑنے والے نئے سینسرز اور مشین لرننگ کی ترقی کے ساتھ سانس یا پیشاب کے غیر تکلیف دہ ٹیسٹ اب کلینک کے قریب نظر آتے ہیں۔ مطالعات میں پھیپھڑوں کے کینسر سے منسلک سانس کے مرکبات، چھ مالیکیولز والا پیشاب کا پینل جس نے 75 فیصد کیسز میں پروسٹیٹ کینسر پکڑا، اور مثانے کے کینسر کا پیشاب ٹیسٹ ملا جسے 2026 میں امریکی فوڈ اینڈ ڈرگ ایڈمنسٹریشن کی بریک تھرو حیثیت ملی، جبکہ الزائمر کا ورژن بھی مئی میں منظور ہوا۔ جلد کے تیل کے اشارے پارکنسنز کے لیے بھی زیر مطالعہ ہیں، لیکن محققین خبردار کرتے ہیں کہ یہ ٹیسٹ ابھی معمول کی تشخیص نہیں ہیں۔
  • वैज्ञानिक लंबे समय से इस बात की जाँच कर रहे हैं कि साँस, त्वचा और मूत्र से निकलने वाले अणु बीमारी का पता लगा सकते हैं या नहीं, यह विचार पाँचवीं शताब्दी ईसा पूर्व में हिप्पोक्रेट्स तक जाता है। अणुओं की छोटी मात्रा पकड़ने वाले नए सेंसरों और मशीन लर्निंग की प्रगति के साथ साँस या मूत्र के गैर-आक्रामक परीक्षण अब क्लिनिक के करीब दिख रहे हैं। अध्ययनों में फेफड़ों के कैंसर से जुड़े साँस के यौगिक, छह अणुओं वाला मूत्र पैनल जिसने 75 प्रतिशत मामलों में प्रोस्टेट कैंसर पकड़ा, और मूत्राशय कैंसर का मूत्र परीक्षण मिला जिसे 2026 में अमेरिकी खाद्य एवं औषधि प्रशासन का ब्रेकथ्रू दर्जा मिला, जबकि अल्ज़ाइमर का संस्करण भी मई में स्वीकृत हुआ। त्वचा के तेल के संकेत पार्किंसंस के लिए भी अध्ययन में हैं, लेकिन शोधकर्ता चेतावनी देते हैं कि ये परीक्षण अभी नियमित निदान नहीं हैं।

Skin oil clues are being studied for Parkinson's too, but researchers caution these tests are not yet routine diagnosis.
