Cancer Care Approach: Diagnostics and Treatment

Cite this

The term “cancer” is used to describe a range of diseases associated with the uncontrolled intense growth of cells that tend to form tumors. Certain factors can cause changes in genes that provoke cancer, and these factors can lead to replicating cells in one of the organs. If these atypical cells invade other organs, this phenomenon is known as metastasis. The types of cancer include breast, lung, prostate, and skin cancer among others (Tobias & Hochhauser, 2015).

While discussing possible factors that can provoke cancer, researchers focus on stress, ecology, and genetic issues (Gaur & Srivastava, 2014). The problem is that specific causes of different types of cancer are understudied to be effectively predicted and addressed. The purpose of this paper is to describe the approach to caring cancer, focus on diagnosing this condition, describe stages of cancer, determine its complications, analyze side effects of treatment, and examine methods of responding to physical and psychological effects.


In many cases, cancer can develop in the organism without specific symptoms and pain, and these aspects make the process of diagnosing cancer complicated. As a result, cancer can be diagnosed at the metastatic stage. In order to diagnose cancer referring to patients’ symptoms, healthcare professionals use the blood test to identify cancer markers pointing out the presence of cancer cells and conduct tests to examine the possible mutation in genes (Miller et al., 2016). Furthermore, they also use screening, X-rays, Magnetic Resonance Imaging, and computed tomography to diagnose lung and breast cancer, for example, and they conduct a biopsy.

The focus on cancer markers like BRCA1, 2 for breast cancer or CA-125 for ovarian cancer is important at the initial stage of developing the disease or when a patient wants to know his or her susceptibility to this or that type of cancer. Screening and different types of imaging are effective when it is necessary to identify possible tumors in different organs and examine metastases (Gaur & Srivastava, 2014). A biopsy is traditionally used for examining cells when solid tumors are present (Tobias & Hochhauser, 2015). In addition, innovative techniques are created by scientists in order to propose more effective methods of diagnosing cancer at the first stage of its development.

Staging of Cancer

There are four stages of cancer that differ in terms of the size of a tumor and the speed of cancer cells’ growth and spread. Stage 1 is associated with the initial stage of growing cancer cells and with a small tumor. At this stage, cancer is not spread to other organs. Surgery at Stage 1 is highly effective to remove tumors (Benitez-Majano, Fowler, Maringe, Di Girolamo, & Rachet, 2016). Stage 2 is associated with the further growth of a tumor or the number of cancer cells in the organ, but at this stage, cancer does not spread to other tissues (Tobias & Hochhauser, 2015). However, depending on the type of cancer, Stage 2 is also related to the initial spread of cancer cells to lymph nodes.

Stage 3 indicates that a tumor is large and cancer cells can be found in the tissues surrounding the affected organ. Stage 4 is associated with metastases as cancer cells are spread to other organs and grow there. There is also Stage 0 that is known as “carcinoma in situ,” and that means the presence of atypical cells in a patient’s body (Tobias & Hochhauser, 2015). This condition can potentially lead to the development of cancer in the future, but at this stage, cancer cells do not form a tumor.

Complications of Cancer

Complications of cancer are various, and they can affect different body systems depending on the type of cancer and its stage. The first type of complications to focus on includes endocrine abnormalities. The development of cancer, the associated treatment, and the emotional state of a patient cause changes in hormone levels that lead to such problems as adrenal insufficiency, hypercalcemia, and hypoglycemia among other conditions.

The associated condition is the development of hematologic problems and risks of thrombosis (Tobias & Hochhauser, 2015). The second possible complication is the problem with the gastrointestinal tract leading to nausea, vomiting, and bleeding. The third group of complications should include interchanged problems, such as pain, fatigue, and mood disorders. Patients suffering from cancer usually experience significant pain, their state causes continuous fatigue, and all these factors lead to the development of such mood disorders as anxiety and depression (Gaur & Srivastava, 2014). Depending on the stage of the disease, these complications can have different symptoms and effects on a patient’s physical and emotional state.

Side Effects of Cancer Treatment

Radiation and chemotherapy are the key types of treating cancer that have numerous side effects. Radiation therapy often causes skin irritation and dryness, tiredness, nausea, diarrhea, difficulties when swallowing, numbness, and problems with teeth among many others that differ with reference to the type of cancer and affected organs. Side effects associated with chemotherapy include hair loss, nausea, bleeding, fatigue, anemia, constipation, difficulties when swallowing, diarrhea, numbness, kidney problems, and changes in weight among others (Miller et al., 2016). Women can suffer from premature menopause and problems with fertility (Tobias & Hochhauser, 2015).

It is important to note that not all patients may observe these side effects when being treated with the help of radiation therapy of chemotherapy, and the presence of side effects depends on the response of a patient’s immune system to the selected therapy. Moreover, one should note that surgery also has side effects, including chronic pain after removing a tumor or tumors.

Decreasing Physical and Psychological Effects

Physical effects of cancer include chronic pain and significant changes in a patient’s and his or her family’s lifestyle. Thus, patients can suffer from pain because their cancer cannot be untreated or as a result of surgery. Moreover, persons with cancer or after treating it can be prescribed to take medicines causing side effects and change their habits regarding their daily life (Tobias & Hochhauser, 2015).

Moreover, the immune system of persons surviving cancer is often affected, causing the development of chronic diseases or frequent cases of infections. These physical effects are usually addressed with the help of prolonged pharmacological therapies and rehabilitation programs that are directed toward improving individuals’ health after surviving cancer (Miller et al., 2016). Therapies oriented to relieving pain are used in cases when individuals suffer from untreated types of cancer.

There are also multiple psychological effects of cancer. They include stress, anxiety, depression, suicidal ideations, and the sense of hopelessness among other problems. In order to address these conditions, patients with cancer usually work with psychologists, counselors, or therapists to learn how to cope with distress and overcome fear associated with their state (Tobias & Hochhauser, 2015).

From this perspective, psychologists and therapists apply a range of methods to work with their patients, including exercises in relaxation, talk therapy, group therapy, training in coping with side effects of treatment, and drug therapy to address depression (Gaur & Srivastava, 2014; Miller et al., 2016). As a result of these methods and strategies, individuals with cancer or surviving it can cope with psychological stress, anxiety, and fear while receiving emotional support and required education.


The care or treatment of cancer depends on timely diagnosis and the selection of the most effective option for this or that cancer type. As it has been stated in this paper, the process of diagnosing cancer is challenging in many situations when this condition is asymptomatic. Therefore, it is important to use different approaches to diagnosing, such as screening, a biopsy, and the test with the focus on cancer markers in order to determine tumors at their first stages of growth. There are four stages of cancer that differ in the development of cancer and its spread in the body. Consequently, diagnosing cancer at the first or second stage is a primary goal for physicians and oncologists.

The paper has also provided the description of typical complications of cancer that need to be taken into account while choosing an appropriate treatment plan. Furthermore, therapies and surgery used for treating cancer also have side effects that should be addressed to improve patients’ state. Finally, while developing treatment plans for individuals with cancer, it is also necessary to include therapies oriented to relieving their pain and improving their emotional state.
