The cost of health insurance claims for cancer treatment among contractors and tradespeople has increased by 84% since 2012 according to ECIS.
The employee benefits company for the construction sector has revealed the average claim cost is now in the region of £7363 compared to £4254 in 2012.
While there has only been a 6% increase in the number of cancer related claims since 2012, in 2015 nearly a quarter (23%) of all health insurance claims paid were related to cancer treatment.
This is an increase from 14% in 2012, putting it in second place behind treatment for muscle, bone and joint conditions.
The analysis was conducted to highlight the importance of seeking advice and guidance at the earliest opportunity when it comes to cancer treatment, ECIS said.
Around 3,700 occupational cancer cases are estimated to arise each year as a result of past exposures to carcinogens through working in construction
Vicki Leslie, client relationship manager at ECIS said: "While on the one hand it is good news we are not seeing an increase in the volume of claims, the increase in cost is a strong indication of the severity of the condition and corresponding treatment.
"Early diagnosis and treatment is key. For example, when prostate cancer is diagnosed at its earliest stage, all men with prostate cancer will survive their disease for five years or more, compared with less than a third of men when diagnosed at the latest stage."
She added: "Survival rates are improving and has tripled in the last 40 years in the UK, probably because of PSA testing, which again highlights the importance of an early diagnosis. Also if breast cancer is diagnosed at its earliest stage, around all women will survive the disease for five years or more, compared to 3 in 20 women when the disease diagnosed at the latest stage.
"Those working in the construction industry may be exposed to various risks on a daily basis, from working outside in the sun to using harmful chemicals, yet research has found that 40% of tradespeople never check themselves for the signs of cancer.
"We urge all workers in the construction industry to seek guidance at the earliest opportunity if they have any concerns so that correct treatment can be identified as soon as possible."
