Specifically, for every four-inch increase in height over 5 feet 1 inch, the risk that a woman would develop cancer increased by about 16 percent, especially for:
• Colon Cancer (RR per 10 cm increase in height 1.25, 95% CI 1.19—1.30)
• Rectal Cancer (1.14, 1.07—1.22)
• Malignant Melanoma (1.32, 1.24—1.40)
• Breast Cancer (1.17, 1.15—1.19)
• Endometrial Cancer (1.19, 1.13—1.24)
• Ovarian Cancer (1.17, 1.11—1.23)
• Kidney Cancer (1.29, 1.19—1.41)
• Brain/Spine Cancer (1.20, 1.12—1.29)
• Non-Hodgkin's Lymphoma (1.21, 1.14—1.29)
• Leukaemia (1.26, 1.15—1.38)
It is hypothesized that the levels of growth hormone responsible for human height might also be involved in cancer development or because taller people are at greater risk for mutations simply because their bodies are comprised of more cells.
The increased cancer risk was found to be also true across Asia, Europe, Australia, and North America populations.
Perhaps now there's a reason why the average female is 5 feet, 3.8 inches tall! It's a balance between social preferences for being tall versus negative biological consequences for being tall.
The good news here (if there's any) is that head and neck cancer does not increase with height.
