Conjunctival Cancers
Conjunctival cancers are cancers that originate from the cells of the conjunctiva, which is the thin, transparent membrane on the surface of the eye. The conjunctiva is a layer that covers both the white part of the eye (sclera) and the inner surface of the eyelids, extending within the eyelid.

Conjunctival Cancers
Conjunctival cancers are tumors known as cancers of the conjunctiva, which is the thin membrane covering the white part of the eye and the inner surface of the eyelids. Conjunctival cancers are rare types of eye tumors and are generally limited to being benign (non-cancerous). However, in some cases, conjunctival cancers can be malignant (cancerous) and have the potential to spread.
Conjunctival cancers typically result from cellular abnormalities that occur in the conjunctiva. There are two main types of conjunctival cancers:
- Invasive Squamous Cell Carcinoma: This is the most common type of cancer involving the conjunctiva. It can be associated with risk factors such as excessive sun exposure, HPV (human papillomavirus) infection, certain genetic factors, and immunosuppressive conditions. Invasive squamous cell carcinoma is a tumor that can be malignant and have the potential to spread.
- Conjunctival Melanoma: This is a rare type of cancer that occurs in the conjunctiva. It arises from the abnormal growth of cells in the conjunctiva that produce pigment. Melanoma can be dangerous and has a tendency to metastasize, similar to skin melanomas.
Symptoms of conjunctival cancers may include redness, swelling in the conjunctiva, lesions, a sensation of grittiness or burning in the eye, itching in the eye, persistent swelling or drooping of the eyelid, blurred or decreased vision, and the growth of a spot or nodule on the eye.
If you suspect conjunctival cancer, it is important to consult an eye doctor. The eye doctor will review your medical history, conduct an eye examination, and may request additional tests such as a biopsy when necessary. After a diagnosis is made, treatment options may include surgical intervention, radiotherapy, or sometimes chemotherapy. Treatment options can vary depending on the type of tumor, its size, and the extent of its spread.
