🚨 BEFORE YOU SHARE THAT "CANCER PREVENTION" MESSAGE ON WHATSAPP… PLEASE READ THIS.
A viral message circulating online claims to be a summary from a medical conference in Berlin and contains statements about cooking oil, powdered milk, Maggi cubes, microwaves, bras, deodorants, sugar, contraceptives and certain "deadly" food combinations.
But here is the problem:
Not everything in that message is medically true.
As pharmacists and healthcare professionals, we must be careful not to turn health advice into health misinformation.
✅ WHAT SCIENCE ACTUALLY SUPPORTS
• Limiting or avoiding alcohol can reduce cancer risk. Alcohol is a recognised carcinogen and is linked to several cancers, including breast, liver, colorectal and oesophageal cancers.
• Eat more vegetables, fruits, legumes, whole grains and other nutrient-dense foods.
• Limit highly processed foods, sugary drinks and processed meats.
• Maintaining a healthy weight and being physically active are important parts of cancer prevention.
• Breastfeeding has been associated with a lower risk of breast cancer in mothers.
• Some hormonal contraceptives can slightly alter breast-cancer risk, but this does NOT mean that all contraceptives "cause cancer." The right contraceptive choice should be discussed with a qualified healthcare professional.
• Use only microwave-safe containers when heating food.
❌ WHAT YOU SHOULD NOT BELIEVE FROM THAT VIRAL MESSAGE
🚫 "Sugar feeds cancer, so stopping sugar makes cancer disappear."
Cancer cells use glucose—but so do normal cells. The National Cancer Institute says there is no evidence that eating sugar makes cancer worse or that completely eliminating sugar makes cancer shrink or disappear.
🚫 "Microwave ovens cause cancer."
There is no good evidence that properly functioning microwave ovens cause cancer. Follow the manufacturer's safety instructions and use microwave-safe containers.
🚫 "Tight bras cause breast cancer."
There is no scientific evidence that wearing a bra causes breast cancer.
🚫 "Deodorant causes breast cancer, especially after shaving."
Current evidence does not support this claim.
🚫 "Pineapple + Coca-Cola is a deadly combination."
❌ False.
🚫 "Banana + egg kills immediately."
❌ False.
🚫 "Banana + milk poisons you."
❌ False.
These combinations may cause digestive discomfort in some individuals, but they do not become a "deadly poison" simply because they are eaten together.
🚫 "Aloe vera + ginger + parsley + celery + pineapple is an anticancer treatment."
There is no reliable clinical evidence that this juice cures cancer. It should NEVER replace proper cancer diagnosis or treatment.
⚠️ ONE MORE IMPORTANT POINT
The message says that mammograms should not be done during pregnancy. That is too broad.
Ultrasound is often preferred during pregnancy, but when there is a concerning breast finding, appropriate diagnostic imaging—including mammography when clinically indicated—may still be necessary. Don't avoid a medically necessary investigation because of a WhatsApp message.
THE REAL LESSON?
Cancer prevention isn't about finding one "killer food" or one magical juice.
It is about making evidence-based choices consistently:
🥦 Eat a balanced diet
🏃♀️ Stay physically active
⚖️ Maintain a healthy weight
🚭 Don't smoke
🍺 Avoid or limit alcohol
🥩 Limit processed meat
🥤 Reduce sugary drinks and highly processed foods
🩺 Participate in appropriate screening
💉 Take recommended cancer-preventing vaccines such as HPV and hepatitis B when indicated
👩⚕️ Seek professional medical advice when you have symptoms or concerns
And please remember:
Not everything forwarded on WhatsApp is a medical report.
Before you forward a health message to 100 people, pause and ask:
"Who said this? Where is the evidence? What do recognised health authorities say?"
Because fighting cancer requires not only medicine…
It also requires fighting misinformation.
📌 Share the facts, not the fear.
