Navigating Breast Cancer Decisions on ‘The Path of Least Regret’

Author and survivor Parul Somani shares how patients with breast cancer can find peace of mind when clinical certainty is missing.

For many patients diagnosed with breast cancer, the immediate aftermath is a whirlwind of clinical data, survival statistics, and a desperate search for the "right" answer. However, Parul Somani, an MIT- and Harvard-trained strategist and breast cancer survivor, argues that in the face of extreme medical uncertainty, certainty is often an illusion.

In her new book, "The Path of Least Regret," Somani draws on her professional expertise and personal journey to offer a framework for decision-making when the stakes are high and the data is incomplete. Diagnosed with aggressive breast cancer at age 31, just days after an emergency C-section, Somani found herself forced to make life-altering choices while her newborn was in the NICU.

Moving from "the right answer" to peace of mind

Somani emphasized in an interview with CURE that the first step in navigating a diagnosis is emotional honesty. Before diving into treatment plans, patients must acknowledge the grief and fear that naturally accompany the news. While hope is vital, Somani notes that "hope isn't a course of action." True empowerment comes from seizing control of the factors within a patient’s reach.

The core of Somani’s approach involves three pivotal questions designed to provide clarity:

  1. What are you optimizing for? Patients often default to a goal of simply "living the longest." However, Somani suggested that the answer is often more nuanced. "It’s not just lifespan, but it’s also health span," she explained. Patients must weigh the benefits of long-term survival against potential toxicities, quality of life, fertility and time with loved ones. Having a defined "North Star" helps guide every subsequent clinical choice.
  2. How do you feel about the options in front of you? As patients consult various specialists, they may receive differing recommendations. Somani encouraged patients to listen to their "nagging feelings" or hesitations about specific treatments. Understanding the clinical differences is important, but acknowledging how those options align or conflict with personal values is equally essential.
  3. Which option provides the most peace of mind? In Somani’s own experience, she felt hesitant about the two standard options presented by her care team. By understanding her priorities, she was able to propose a "third option": starting with a less aggressive chemotherapy regimen while closely monitoring the tumor's response. This allowed her to balance recurrence risk with her desire to minimize long-term toxicity.

Regret as a compass

Somani reframes regret not as a failure to avoid, but as a tool for navigation. When "guarantees" do not exist, the goal shifts toward making decisions that the patient can live with, regardless of the eventual outcome. By focusing on meaning, agency, and self-trust patients can move forward with the confidence that their choices were rooted in their own unique values.
