Forward said the collection couldn't take place without the support of volunteers, including large contingents from Whanganui City College and woman's group Zonta.
"My wonderful collectors that collect every year, there's quite a few of them who come back time after time. They're fabulous people.
"Both City College and Zonta help us so much. They both cover a whole site for a whole day, and that's wonderful."
Asked how much the appeal hopes to raise, Forward was unsure where exactly a total would end up, but hopes it will be on par with previous years.
"To be honest, we have no idea this year. Covid hit hard in Whanganui, but we are hoping for at least as much as last year.
"We'll be covering most sites from 8am, and some will go right through til 6pm."
Forward says the work of the Breast Cancer Foundation in the community is essential, with rates of cancer diagnosis rising.
"It's vital. Rates are increasing, and there is a huge percentage of women who have ongoing problems.
"It is vital that we are able to catch it and cure it."
According to the Breast Cancer Foundation, about 40 women in the Whanganui District are diagnosed with breast cancer each year, and about 11 of those will die from the disease.
The street appeal will take place on Friday and Saturday, with collectors based along Victoria Ave and supermarkets around Whanganui. People can also text PINK to 4499 to make a $3 donation.
