How Does Raising Awareness Help?

Awareness days can effectively increase discourse, but more action can help. For instance, these days often focus solely on awareness-raising behaviors (e.g., encouraging people to wear a particular color that day), and not enough people take actionable measures.

Wearing a particular color can be a valuable act of empathy, solidarity, and comfort, but there is an important lesson to be learned here. If you're taking part in cancer awareness activities, having some specific goals in mind that you want to contribute to achieving can be even more impactful.

How to Raise Awareness

There are plenty of ways you can raise awareness about cancer:

  • Post on social media
  • Discuss with friends, family, and coworkers
  • Attend or hold events
  • Call or email politicians
  • Write blog posts or articles for your local paper
  • Reach out to local journalists
  • Volunteer
  • Make donations

Cancer is still one of the most serious problems facing the world today. Advancements in science and medicine, public awareness of risk factors, preventative measures, and the importance of early detection have all contributed to greater treatment success, faster recovery, and survival.

World Cancer Day Initiatives

The World Cancer Day initiative offers many ways to help make real change across the globe by improving education and catalyzing personal, collective and government action. Some of these actions include:

  • Increasing knowledge about prevention
  • Promoting equal access to cancer diagnoses and treatment
  • Reducing the economic and financial impact of cancer

What Preventative Measures Can You Take?

There are many steps you can take in your life to improve your health and wellbeing and to decrease your risk of getting cancer, like:

  • Avoiding tobacco products
  • Drinking alcohol in moderation
  • Limiting processed meats in your diet
  • Maintaining a healthy weight
  • Protecting yourself from the sun
  • Vaccinating yourself against viral infections
  • Practicing safe sex
  • Not sharing needles
  • Performing regular self-exams
  • Visiting with your doctor and dentist regularly for checkups
  • And practicing good oral hygiene

Oral cancer shares many risk factors with other cancers. Increased awareness about oral cancer is essential to promote early detection.

How Does Cancer Treatment Affect Your Mouth?

Certain oral complications may occur as a result of cancer treatments. Visiting a trusted dental professional before beginning treatment for cancer can help you develop a plan that keeps your oral health in tip-top shape.

Some cancer therapy side-effects you'll need to look out for include:

  • Tooth decay and gum disease
  • Inflammation in the mouth
  • Dry mouth
  • Dehydration
  • Loss or changes in taste
  • Mouth and jaw pain

Signs of Oral Cancer

Oral cancer develops in the lips, tongue, inner cheeks, gums, the floor of the mouth, throat and sinuses. An oral cancer screening should be part of a routine oral exam. Schedule an appointment with a dental professional if any of the following oral cancer symptoms last more than two weeks:

  • Mouth pain
  • Lip or mouth sores that don't heal
  • Difficulty swallowing
  • Soreness in the back of the throat
  • Lumps in the mouth
  • Loose teeth
  • Oral thrush
  • Loss of feeling in the mouth
  • Ear pain

Practicing Good Oral Hygiene

Proper oral hygiene behaviors for reducing risks for oral cancer may include the following:

  • Brushing your teeth twice a day
  • Using a tongue scraper once a day
  • Rinsing with an antimicrobial mouth wash
  • Having an oral cancer screening by your dental professional at check-up appointments

Cancer awareness days are a valuable tool for combating some of the world's most serious issues. Whether you donate money to charitable foundations, volunteer your time, or spread the word about a cause you care about, contributions of every size have a real impact on decreasing cancer prevalence—and that's something to smile about for everyone.
