Slade family representative Paul Slade said the Nell and Herman Slade Trust was pleased to support Cancer Care Western NSW.

"The donations provide assistance to the valuable work given by Cancer Care Western NSW at Western Care Lodge in supporting guests that attend from as far away as Cobar, Coonabarabran and down as far as Lake Cargelligo and Young," Mr Slade said.

"We send our good wishes for ongoing successful activity."

Cancer Care Western NSW regional funding and marketing coordinator Jan Savage said the lodge is in its ninth year of operation and has provided accommodation to more than 3500 guests while they received cancer treatment at Orange hospital.

She said the Nell and Herman Slade Trust has supported the lodge since before it was ready for occupation but the amount donated was confidential.

"The lodge was completed in late October 2011 after a successful fundraising campaign by Cancer Care Western NSW which commenced in early 2007," Mrs Savage said.

"The lodge was built in two stages which comprises 22 rooms as well as large communal, living room, outdoor spaces, library, laundries and kitchen areas.

She said the total cost of the completed building was $5.4 million.

"The organisation continues to provide ongoing support with additions to patient comfort and upgrading at Western Care Lodge when required With the guests arriving from a large service catchment area and many staying for up to eight weeks at a time," Mrs Savage said.

"It is important to ensure that their home away from home is maintained within the wonderful garden space that the lodge has, with easy access to hospital services.

Mrs Savage said that in addition to the lodge, Cancer Care Western NSW has contributed $330,000 towards seed funding for the Clinical Cancer Trials at Orange hospital in 2016.
