I wrongly explained a question.i noticed a rough patch on my tongue but its not visible it just feels a bit rougher.no lesion.can this be oral cancer?

Probably not: But it is always recommended to get Oral cancer screening done once every two years at the minimum. So if you are due for one, it will be a very good idea to visit your dentist and also get an examination

Leukoplakia call DDS: generally developed due to irritation from tobacco, rough teeth, fillings, or crowns rub against your tongue. Most patches improve on their own. However, a biopsy is always warranted. See your dentist for evaluation and treatment if needed.

Get It Checked: Some oral cancers and pre-cancers are difficult to see. They are especially hard to see in your own mouth. Your dentist will have better lighting and be able to examine your mouth. Don't hesitate. Most oral cancers can easily be treated, when detected early. They can be deadly, if left too long.
