Acinic cell carcinoma, a common parotid tumor, occurs in people in their 40s and 50s. (merckmanuals.com)

Not to forget the rest of the ocular examination including visual acuity, color vision, assessment of the pupil for Relative Afferent Pupillary Defect, Schirmers specifically for Lacrimal Gland Tumors, basic ocular examination, specific cranial nerve examination and if you think that the tumor is a secondary one, rising from the nasal cavity or Paranasal Sinuses then we have to do oral and nasal examination as well.

Gradual onset of unilateral proptosis with nasal globe displacement with palpable lacrimal gland mass should warrant radiologic imaging and evaluation by an oculoplastic surgeon for possible excision. (logicalimages.com)

Tumours arising from the submandibular gland, sublingual gland, or the minor salivary glands are usually more likely to be malignant (cancerous). (drjkluge.co.za)
