Thyroid cancer occurs when abnormal cells in the thyroid gland begin to divide and grow in an uncontrollable way.
In a recent study, researchers believe that those who live in highly lit areas may have an increased risk of developing the disease. The researchers found that these individuals had low levels of melatonin as a result of the light and thus had an increased risk of infection.
And researchers from the University of Texas Health Sciences Center found that those who live in an area with high levels of artificial light outdoors can increase their chance of developing thyroid cancer.
And the scientists found a possible link between those who contracted the disease and artificial outdoor lighting levels.
Looking at data from 464,371 participants, the study was conducted over a period of 13 years.
And those who live in areas with the highest level of nocturnal light pollution have been found to have a 55% higher risk of developing thyroid cancer than those who live in areas with low lighting.
The researchers hypothesized that the link might be due to night light that inhibits melatonin, and it might have an anti-tumor effect.
Studies have also reported an association between elevated satellite levels of nightlight and a higher risk of breast cancer.

Light at night can disrupt the internal body clock (or circadian rhythms), which is a risk factor for various types of cancer.
“When compared to the lowest fifth of light at night, the top fifth was associated with a 55% risk of thyroid cancer. The main reason behind the association is the most common form of thyroid cancer, which is called papillary thyroid cancer,” said lead author Qian Xiao of the study. It was stronger for women than for men. “
The correlation appears to be similar for different tumor sizes, and in participants with different demographic characteristics and BMI.
The researchers noted that additional studies are needed to confirm their findings.
Symptoms of thyroid cancer include:
Swollen glands in the neck.
• Unexplained hoarseness that does not improve after a few weeks.
Sore throat that doesn’t get better.
Pain in your neck.
Difficulty swallowing.
• Breathing difficulty.
