Mutations01:35

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for electronic transitions. As a result...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
The Electromagnetic Spectrum01:24

The Electromagnetic Spectrum

Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

Area of Science:

  • Dermatology and Oncology
  • Public Health
  • Environmental Health

Background:

  • Ultraviolet (UV) radiation, primarily from solar radiation, is a known human carcinogen.
  • Artificial UV sources, like tanning salons, pose increasing health risks, especially with youth usage.
  • UV exposure is linked to various skin cancers, with different exposure patterns correlating to specific cancer types.

Purpose of the Study:

  • To review the relationship between UV radiation exposure and cancer risk.
  • To highlight the impact of UV radiation on skin cancer incidence and mortality.
  • To explore potential protective measures and emerging research on UV radiation and other cancers.

Main Methods:

  • Review of existing scientific literature on UV radiation and cancer.
  • Analysis of epidemiological data on UV exposure and cancer incidence.
  • Examination of studies on the role of vitamin D in cancer risk.

Main Results:

  • UV radiation is a major cause of skin cancers (melanoma, basal cell, squamous cell) and lip cancer.
  • Intermittent UV exposure is linked to melanoma and basal cell carcinoma, while cumulative exposure relates to squamous cell and lip cancers.
  • UV radiation may have an inverse relationship with certain non-Hodgkin lymphoma, colon, breast, and prostate cancers, potentially due to vitamin D production.

Conclusions:

  • Sun protection, avoiding sunburn, and sunscreen use can prevent a significant portion of UV-related cancers.
  • Early diagnosis of melanoma dramatically reduces mortality rates.
  • While vitamin D may offer some cancer protection, current evidence does not support altering UV exposure policies; further research is warranted.
