Skin cancer occurs due to the abnormal growth of skin cells. Most forms of skin cancer occur due to excessive exposure to UV radiation. It can because of chronic sun exposure as well. Additionally, excessive use of tanning beds can trigger skin cancer. However, these are not the only causes. Skin cancer can also occur in areas which are not exposed to external agents. For example, genital areas, soles of the foot, between the toes, and inside of the mouth may also develop skin cancer. Environmental and genetic factors play a significant role in the development of this disease. All these factors can cause DNA mutation in skin cells, leading to skin cancer. The type of skin cancer depends on the skin cells affected. Read on to know more about the different forms of skin cancer. Basal cell carcinoma: Basal cells are found at the bottom of the outermost layer of the skin, known as the epidermis. The function of these cells is to produce new skin cells. Under regular circumstances, the old cells die and then slough off. This process is controlled by a DNA present in the basal cell. In some cases, the DNA may undergo mutation due to chronic sun exposure, arsenic exposure, immune-suppressing medications, rare genetic diseases, and radiation therapy.

Schizophrenia is a severe and chronic mental disorder that affects the way a person thinks, feels, and behaves. People who have been diagnosed with this condition, seem to have lost touch with reality. The condition develops slowly, making it hard to identify initial signs and symptoms. The symptoms of schizophrenia are classified into two basic types: Positive symptoms Positive symptoms are any changes in the thoughts or behavior like delusions or hallucinations. Negative symptoms A lack of function or withdrawal that would not usually be expected to see in a healthy person, as people with schizophrenia often appear emotionless. The most common symptoms of schizophrenia are as follows. Hallucinations Hallucinations are when someone sees, feels, hears, tastes, or smells things that only exist in their mind. One of the most common hallucinations experienced is hearing voices. Hallucinations feel extremely real to the person who is experiencing them. Other people cannot experience these sensations. According to some research, using brain-scanning equipment has shown some changes in the speech area in the brains of people who have been diagnosed with schizophrenia when they hear voices. It has been observed that the thoughts of the brain are mistaken as real voices. Few people describe the voices as pleasant and friendly.

Sleep apnea causes a short supply of oxygen to the brain and other parts of the body. The interference in breathing during sleep can be a potential cause of many medical conditions such as high blood pressure, diabetes, heart failure, depression, worsening of ADHD, headaches, and stroke. If left untreated, it will also have many adverse effects on daily activities. It may lead to vehicle accidents, underachievement in schools and workplaces. Treatment is recommended by the doctor based on the evaluation of signs and symptoms of sleep apnea. An evaluation often involves overnight monitoring of the body functions during sleep. Some of the effective treatment procedures include; Lifestyle changes Doctors may recommend only lifestyle changes for milder cases of sleep apnea. Losing excess weight and quitting smoking and avoiding abuse of alcohol are the basic lifestyle changes that may be expected from patients. Treatment for allergies If an individual suffers from nasal allergies, they should be treated appropriately. Nasal allergies cause blockage in the airway and make breathing difficult. Continuous positive airway pressure (CPAP) If the sleep apnea condition is moderate to severe, CPAP mask may be recommended to give pressure to the air passing through a blocked nose. Oral appliances Oral appliances help to keep the throat open.
