Is there any efficient home remedy to prevent me from getting throat cancer?

Simply put. There are benign causes and worrisome ones. If the frequency is unusual and lasting longer than a minute or two, I would advise you to get it checked. At the A&E, our practice would be to first examine where the bleeding occurs, if it’s at the front and easily seen it’s usually due to mucosal injury be it nose digging or blowing your nose very hard. Some medicines like acne medications can cause dry mucosa, as can cold weather and climates.

You can try and persuade your dad to seek help by trying to assuage his fears. Fearing it is a cancer, he may not want to seek treatment. You can let him know that most of the time, the hoarseness can be from gastroesophageal reflux disease (GERD) which happens more in elderly, if there are irregular or late meals, intake of too much alcohol and sour, fried, oily or spicy foods. After a simple flexible scope that goes through the nose down the throat, which really takes only 1 minute, the diagnosis is made in the clinic.
