A non-invasive, skin cancer detection device for physicians.

Optical tissue samples are objectively analyzed, with results in seconds not days.

How It Works

Lesion Identification

Lesion Identification

Physician identifies the lesion of concern on their patient
DermaSensor Scan

DermaSensor™ Scan

Physician gently touches the small device tip to the lesion, taking instant recordings at different locations of the lesion
Photo Scattering

Photon Scattering

Light reflects and scatters from particles in the cells of the skin tissue back to DermaSensor’s™ spectral sensor
Algorithmic Analysis

Algorithmic Analysis

The proprietary DermaSensor™ algorithm analyzes the reflected photons and provides an immediate “Investigate Further” or “Monitor” result

DermaSensor™ Technology

  • DermaSensor’s™ tip reflects and records quick bursts of light off the lesion’s cellular and sub-cellular content.
  • The light is analyzed by the built-in computer to provide information to help physicians assess skin lesions (including melanomas, squamous cell carcinomas, and basal cell carcinomas) to aid in a referral decision.
  • By examining the difference in light scattering, DermaSensor™ determines if the skin lesion is “Further Investigate” or “Monitor,” an immediate output.
  • Elastic Scattering Spectroscopy (ESS) has been validated in 30+ publications on clinical studies. Many studies have shown ESS to provide information that is comparable to histopathologic assessment in the analysis of cellular microscopic structure.1-4, 15-21
About ESS

DermaSensor™ uses Elastic Scattering Spectroscopy (ESS), a process which evaluates how photons scatter when reflected off of different cellular structures. Malignant lesions have been reported to have different cellular and sub-cellular structures than benign lesions, scattering light differently.

DermaSensor™ for Physicians


Each year ~5,500,000 skin cancers are diagnosed in America making skin cancer more common than all other cancers combined5,6,7. Unfortunately, only 15% of Americans report having ever been screened for skin cancer8 and, even with that low rate, the average wait time for a dermatologist is still 32.3 days9.


While the 5-year survival rate is 98.7% for early-stage localized melanoma, it is only 24.8% for late-stage distant melanoma (metastasized to other organs)10. In addition, the total treatment costs for melanoma in situ is ~$4,648 while Stage IV melanoma is ~$159,808*11.


Effective evaluation of patients with potential skin cancer in primary care is hampered by limited consultation time and limited dermatology training. PCPs will be able to use DermaSensor™ as an adjunctive tool to better assess skin lesions and determine whether additional evaluation is needed.

What is an Adjunctive Tool?

An adjunctive tool, also known as a clinical decision support tool, is not meant to replace clinicians’ decision-making. DermaSensor™ will provide clinicians with additional information about a lesion for them to consider in their referral decision. An adjunctive tool is not a diagnostic, so DermaSensor™ does not definitively determine whether or not cancer is present, specify what type of cancer may be present, nor make any decision for the user.

DermaSensor™ Benefits

  • DermaSensor™ quickly assesses information below the skin surface to give physicians more information and confidence in their decision-making.
  • DermaSensor™ is designed to improve early detection of skin cancer through its earlier referral to dermatologists.
  • Patients are expected to view DermaSensor™ as a supplemental and valuable addition to the skin care they already receive.
  • The non-invasive nature of DermaSensor™ is expected to be unintimidating to patients and reassure them that they are receiving high-quality care.
  • The machine-learning algorithm is derived from thousands of spectral samples of pathologically-verified lesions and is trained by expert data scientists.

Why PCPs Care About Skin Cancer In Their Practice

PCPs Care

1 in 5 Americans are diagnosed with skin cancer in their lifetime.7

PCPs Care

Annual cost of treating skin cancers in the U.S. is estimated at $8.1 billion, with an estimated 5.5 million new cases of skin cancer each year.5,6,12

PCPs Care

42.7% of patients present with at least one skin condition to their primary care physician.13

PCPs Care

Primary Care Physicians refer as few as 54% of the cancerous lesions they evaluate.14
