Which two strata of the epidermis are most susceptible to cancer?

Strata spinosum and strata basale.

Explanation:

Cancer is the abnormal growth of the cell that might occur due to the mutation in gene responsible for apoptosis and proto oncogenes. The cancer cells loses the apoptosis property.

The srtatus basale is the only layer of the epidermis that has the ability to divide mitotically and more prone to cancerous cell. The spinosum is the other layer of the epidermis that can cause cancer is comes in contact with the harmful radiation.

Thus, the correct answer is strata spinosum and strata basale.

The correct answer is - strata spinosum and strata basale.

Explanation:

The two strata of epidermis that are prone to the cancer are stratum basale and stratum spinosum. The stratum basale is the major stratum layer as it is only layer that can divide and mitotically active.

The other major layer that is succeptible to cancer is spinosum as it allows the maturation of the keratinocytes. The major culprit is UV light, however other causes such as radiation and arsenic can also cause cancer.

Thus, the correct answer is - strata spinosum and strata basale.
