According to the National Cancer Institute, a tumor is an unusual tissue mass that results from cell division beyond what is naturally expected. Tumors may also develop when divided cells do not die as due. Tumors sometimes look like cancers. However, not all tumors are cancerous. The human body is made up of cells that grow, multiply and take the place of each other. As new cells appear, old cells disappear. So cancers are formed when the body starts to produce cells that it does not need. When these cells become too much, swellings and tumors begin to develop. Different types of tumors might develop in the human body. There are three broad categories of tumors: malignant, premalignant, and benign tumors. Malignant tumors are cancerous, and when not adequately treated, they can spread to other parts of the body. Benign tumors, on the other hand, are non-cancerous cells. Benign tumors, otherwise called non-cancerous tumors, pose little to no threat to a person's health. Unlike malignant tumors, they do not usually spread to other body parts. It has been noted that most benign tumors do not need to be treated as long as they are not painfully pressing against other body parts. Different types of benign tumors can grow in the human body. One of them is benign bone tumors like osteomas. While osteomas are not cancerous, they might result in a severe kind of pain if it does not receive instant medical attention. Similarly, brain tumors like meningiomas and schwannomas are also examples of benign tumors. Meninges are tissues that cover the brain and the spinal cord, and they are also hosted. On the other hand, malignant tumors, otherwise known as cancerous tumors, tend to spread to other tissues or organs. For instance, they could spread to other body parts like organs and tissues. The newly formed cells are known as metastases. While most people tend to remove malignant tumors, they might reappear through a process known as cancer recurrence. There are different types of malignant tumors. Osteosarcoma and chordomas are two types of m, malignant tumors that grow in the brain. On the other hand, the various organs in the body might develop tumors like pancreatic cancer and lung cancer. Similarly, the skin might also develop malignant cancers like squamous cell carcinoma. Premalignant tumors are also a type of tumor. Unlike both tumors mentioned earlier, this kind of tumor can either be malignant or none malignant. So its malignancy is based on whether it is treated as soon as possible. Premalignant tumors need to be closely m monitored by a doctor, or they might become cancerous.

2. Introduction
According to the National Cancer Institute, a tumor is an unusual tissue mass that
results from cell division beyond what is naturally expected. Tumors may also
develop when divided cells do not die as due. Tumors sometimes look like cancers.
However, not all tumors are cancerous.

3. The human body is made up of cells that grow, multiply and take the place of each
other. As new cells appear, old cells disappear. So cancers are formed when the
body starts to produce cells that it does not need. When these cells become too
much, swellings and tumors begin to develop.

4. Different types of tumors might develop in the human body. There are three broad
categories of tumors: malignant, premalignant, and benign tumors. Malignant
tumors are cancerous, and when not adequately treated, they can spread to other
parts of the body. Benign tumors, on the other hand, are non-cancerous cells.

5. Benign tumors, otherwise called non-cancerous tumors, pose little to no threat to a
person's health. Unlike malignant tumors, they do not usually spread to other body
parts. It has been noted that most benign tumors do not need to be treated as long as
they are not painfully pressing against other body parts.

6. Different types of benign tumors can grow in the human body. One of them is benign
bone tumors like osteomas. While osteomas are not cancerous, they might result in a
severe kind of pain if it does not receive instant medical attention. Similarly, brain
tumors like meningiomas and schwannomas are also examples of benign tumors.
Meninges are tissues that cover the brain and the spinal cord, and they are also
hosted.

7. On the other hand, malignant tumors, otherwise known as cancerous tumors, tend to
spread to other tissues or organs. For instance, they could spread to other body parts
like organs and tissues. The newly formed cells are known as metastases. While most
people tend to remove malignant tumors, they might reappear through a process
known as cancer recurrence.

8. There are different types of malignant tumors. Osteosarcoma and chordomas are two
types of m, malignant tumors that grow in the brain. On the other hand, the various
organs in the body might develop tumors like pancreatic cancer and lung cancer.
Similarly, the skin might also develop malignant cancers like squamous cell
carcinoma.

9. Premalignant tumors are also a type of tumor. Unlike both tumors mentioned
earlier, this kind of tumor can either be malignant or none malignant. So its
malignancy is based on whether it is treated as soon as possible. Premalignant
tumors need to be closely m monitored by a doctor, or they might become cancerous.

10. An example of a premalignant tumor is actinic keratosis or solar keratosis. Actinic
keratosis leaves the skin with patches and scaly swellings. Excess sun exposure is
one of the risk factors associated with arctic keratosis, and it affects people with a
fairer skin than it does other skin types.

11. Cervical dysplasia is another premalignant tumor that might grow in the human
body. This tumor involves a swelling in the body's cells that eventually results in the
cervix lining. Cervical dysplasia is a product of human papillomavirus (HPV), and
young people have a higher likelihood of contracting the virus.
