I have painless hard lump in my tongue for the past 2 years. Could this be cancerous?

Oral candidiasis is a common, opportunistic infection caused by intraoral, commensal yeast atrophic glossitis.

For all patients with an oral lesion, we perform a focused clinical history, with attention to the 1. Location of the lesion (e.g., the involvement of tongue only, all oral mucous membranes involved). 2. Color and quality of the lesion (hyperpigmented, erythematous, white, bullous, erosive/ulcerated, macular versus papular). 3. Duration of time the lesion has been present (if noticed). 4. Change in color or size of the lesion (eg, enlargement, waxing and waning of lesion size, periodic recurrence with resolution in-between episodes) 5. Associated local symptoms (bleeding, discharge, irritation, discomfort or pain, enlargement of local lymph nodes). 6. Systemic complaints (fever, rash, arthralgias or arthritis, unintentional weight loss). 7. Medications, including any recent medication changes and the use of any intraoral (topical) preparations. 8. Tobacco use (including smoking and smokeless tobacco products), enquiring about current use and tobacco history. In addition, we enquire about chewing betel quid, or paan (a combination of areca nut, spices, and tobacco that is popular in many parts of Asia). 9. Alcohol consumption, including current use and history of alcohol use. 10. Medical history, including any known autoimmune disease, malignancy (including history of previous bone marrow transplant), immunosuppression (infection with HIV, active cancer treatment, immunosuppressive medication). 11. Dental work, including the use of dental appliances (dentures) and the presence of amalgam fillings (silver fillings that contain elemental mercury). Physical examination – In addition to the clinical history, we perform a careful intraoral and extraoral examination. Intraoral examination: we perform both a tactile and visual inspection of the oral cavity using gloved hands under adequate illumination. Before the examination, we ask patients to remove dental appliances (dentures), although examination with the appliance in place can also provide useful information, particularly when a traumatic lesion is suspected. The oral lesion is carefully inspected with attention to the location, color, size, and quality (pigmented, ulcerated) and palpated for texture (soft versus indurated) and tenderness. We then systematically examine all oral structures in a consistent sequence. We use both hands, utilizing gauze to grasp the tongue during the examination to adequately visualize the entire oral cavity and vestibule. Extraoral examination: for all patients with oral lesions, in addition to a thorough intraoral examination, we perform a focused examination of the perioral area, including visual inspection of the lips and skin of the face and neck. Observation for any asymmetry, swelling, or masses of the face or neck. Palpation of head and neck lymph nodes, with particular attention to the anterior and posterior cervical, pre and postauricular, submandibular, submental, parotid, and buccal lymph nodes.

White or red oral lesions include benign lesions (morsicatio buccarum and frictional keratosis, white sponge nevus WSN), benign lesions with malignant potential (erythroplakia, leukoplakia, oral lichen planus and other lichenoid lesions, submucous fibrosis, actinic cheilitis). Oral candidiasis is a common, opportunistic infection caused by intraoral, commensal yeast.
