If you’re planning to have cancer surgery in the near future or recently had surgery, your thoughts undoubtedly move to how you can minimize the trauma and scarring associated with treatment and speed the healing process. Healing wounds whether from accidental injury or surgical intervention requires a delicate interplay of multiple cell types, nutritional factors, immune processes and growth factors. Proper planning and prompt attention can promote normalization in appearance.
Healing -From the Inside Out
Wound healing is a stepwise process involving hemostasis, inflammation, and remodeling. During hemostasis, blood platelets release clotting factors and growth factors to help the body create a protective wound scab. This barrier provides a surface beneath which cell movement can occur. Then the process of inflammation brings nutrients to the area, removes debris and bacteria, and provides chemical signals for wound repair. Healing proceeds only after inflammation is controlled. The repair process can then begin to build new skin, fibrous tissue and blood vessels.
Deficiencies of proteins, vitamins, minerals and fluids may significantly impair the healing process. Vitamin C (ascorbic acid) found in citrus fruits, tomatoes, green peppers is required for the formation of the connective tissue protein collagen. The precursor to Vitamin A (retinol) is found in carrots, cantaloupe, tomatoes, eggs, butter and cheese. It is essential for cell growth, skin and bone formation and immunity. The body uses glucosamine to build connective tissue. Adequate dietary protein is necessary to build new tissue. Surgical trauma produces a sharp decrease in serum zinc concentration. Zinc is an important cofactor for enzymes that control the collagen matrix. It has demonstrated anti-infective action, inhibits formation of reactive oxygen species and promotes skin formation.
Healing- From the Outside In
Topical vitamin E and ascorbic acid, calcium D-pantothenate and fibronectin can speed wound healing. Other novel approaches involve topical application of a mixture of various growth factors (PDGF, TGF-beta, PDAF, PF4, PDEGF) to slow healing wounds although the marketplace has only supported the use of platelet derived growth factor (PDGF-BB). Skin graft donor site healing time has been reduced by 1 day using topically applied epidermal growth factor (EGF). (Komarcevic) Zinc oxide in paste bandages (Unna boot) protects and soothes inflamed skin. Topical administration of zinc appears to be superior to oral therapy due to its action in reducing superinfections and enhancing local defense systems.
Pressure is thought to decrease tissue metabolism and increase collagen breakdown within the wound. Silicon gel sheets (applied for 12 hours/day) add pressure and are also thought to work by hydrating the scar tissue. Rehydration softens the scar, thereby making it more flexible and improving the natural repair and flattening process. The newer the scar, the better the result. Onion extract (Mederma) has shown improvement for hypertrophic and keloids scars. However, it was ineffective in improving scar height and itching. For this reason, onion extract therapy should be used in combination with an occlusive silicon dressing to achieve a desirable decrease in scar height. Aquaphor is a petroleum based product that has been shown to speed healing of damaged skin.
In summary, each phase of tissue repair can be influenced by nutritional, biological, botanical factors and mechanical approaches.

Cancer is a significant factor in slowing wound repair. Processes intrinsic to cancer, such as hormonal disregulation, chronic inflammation, nutritional deficits, etc. work against the repair process. However, addressing these clinical issues and integrating the above approaches can improve the wound repair process.

The milk harvested for this product comes from cows that graze on pesticide and chemical-free natural grass pastures. Milk from grass-fed cows has many times higher levels of CLA and contains a proper balance of essential fatty acids. The milking cows are never fed grain or subjected to any growth hormone treatment, chemicals, antibiotics, genetically modified organisms, hyperimmunization or injected pathogens.
This whey protein is produced using a unique low temperature drying and filtration method. The vast majority of whey proteins available use high heat pasteurization. High heat does irreversible damage to the majority of the components of milk and may cause intolerance even in individuals who have no history of milk allergies.
