How Familiar Are You With Oral Cancer?

Explanation
Oral cancer is also known as mouth cancer because it specifically refers to cancer that develops in the tissues of the mouth. It typically starts as a sore or growth in the mouth that does not go away and can spread to other parts of the body if not treated. Lung cancer, leukemia, and brain tumor are different types of cancer that affect other areas of the body and are not synonymous with oral cancer.

Explanation
The given answer, 2013, is the correct answer because it is the year in which oral cancer resulted in 135,000 deaths. This is an increase from the 84,000 deaths in 1990, indicating a significant rise in the number of deaths due to oral cancer over the years.

Explanation
The correct answer is 63% because it is the highest survival rate among the options provided. This suggests that, on average, a higher percentage of individuals in the United States survive for at least five years after their initial diagnosis of a particular condition or disease.

Explanation
The tongue is used for tasting. It contains taste buds that can detect different flavors such as sweet, sour, salty, and bitter. The taste buds send signals to the brain, allowing us to perceive and differentiate between various tastes. The other options, teeth, lips, and alveolar ridge, do not directly contribute to the sense of taste. Teeth are used for biting and chewing food, lips help with speaking and protecting the mouth, and the alveolar ridge is a bony ridge behind the upper front teeth.

Explanation
Teeth can be divided into four types: incisors, canines, premolars, and molars. Incisors are the sharp, flat-edged teeth at the front of the mouth used for cutting and biting. Canines are the pointed teeth on each side of the incisors, used for tearing and gripping food. Premolars are the teeth located behind the canines, used for grinding and crushing food. Molars are the largest teeth at the back of the mouth, also used for grinding and chewing food. Therefore, the correct answer is 4.

Explanation
In 2014, the British Cancer Research found 2386 deaths due to oral cancer. This suggests that oral cancer was a significant cause of death in that year. It is important to conduct research and raise awareness about oral cancer to prevent further deaths and improve treatment options.

Explanation
In the UK, only 6% of people under the age of 45 are affected by oral cancer. This suggests that individuals who are younger than 45 have a lower risk of developing oral cancer compared to older age groups. It is important for individuals of all ages to be aware of the risk factors and symptoms of oral cancer, and to maintain good oral hygiene and regular dental check-ups to detect any potential issues early on.

Explanation
The mouth is primarily used for talking as it is the main organ involved in producing speech sounds. It contains the vocal cords, tongue, and lips which work together to form different sounds and words. While the mouth can also be used for other activities such as eating and drinking, the ability to communicate through speech is its most important function.

Explanation
The mouth is the first portion of the alimentary canal where food enters the body. It is responsible for receiving food and beginning the process of digestion by producing saliva. The mouth contains various structures such as the teeth, tongue, and salivary glands, which aid in the breakdown of food and the formation of a bolus that can be swallowed and further digested in the stomach and intestines.

Explanation
The mouth consists of two regions.
